The Microsoft 77-428 Exam, "Excel 2013 Expert Part Two," is the final step in achieving the prestigious Microsoft Office Specialist (MOS): Excel Expert certification for the 2013 version. This exam is designed for individuals who need to perform advanced data analysis, modeling, and visualization. It moves beyond the scope of traditional Excel functions and focuses heavily on the powerful business intelligence (BI) tools integrated into the software. The target audience includes business analysts, data professionals, finance experts, and anyone whose role requires them to transform large, complex datasets into actionable insights.
Passing the 77-428 Exam demonstrates a mastery of Excel's most advanced capabilities. It signifies that you can not only create complex formulas and charts but also build sophisticated data models, import and transform data from multiple sources, and create compelling, interactive dashboards. This certification is a formal validation of your ability to leverage Excel as a true business intelligence platform, making it a highly valuable credential for any professional working in a data-driven field. The exam is practical and project-based, requiring hands-on proficiency.
A core concept that is absolutely central to the 77-428 Exam is the Excel Data Model. Traditionally, analysis in Excel was often limited to a single, flat table of data. To analyze data from two different tables, you would typically have to use functions like VLOOKUP to manually combine them, which is inefficient and impractical for large datasets. The Data Model overcomes this limitation by allowing you to build a relational data structure directly within your Excel workbook.
The Data Model essentially acts like a small, in-memory database. It allows you to import multiple tables of data and, most importantly, define relationships between them. For example, you can have one table of sales transactions and another table of product information and create a relationship between them based on a common "Product ID" column. This enables you to create PivotTables and other reports that seamlessly combine data from both tables without ever having to merge them manually.
Before you can model your data, you first need to get it into Excel. The 77-428 Exam requires proficiency with Power Query, which is the primary tool for this task. Power Query (which was available as a free add-in for Excel 2013) is a powerful data connection and transformation tool. It allows you to connect to a wide variety of data sources, such as text files, databases (like SQL Server or Access), web pages, and other Excel workbooks.
Once you have connected to a data source, the Power Query Editor opens. This is where you perform the "transform" steps to clean and shape your data before you load it. Common transformations include removing unnecessary columns, changing data types, filtering out unwanted rows, splitting columns, and creating new custom columns based on formulas. This process of extracting, transforming, and loading (ETL) data is a foundational skill for the 77-428 Exam.
After you have cleaned and transformed your data in Power Query, you have a critical choice to make: where to load the data. You can load it to a standard Excel worksheet, but for the purposes of the 77-428 Exam, the more important option is to load it directly into the Data Model. When you choose this option, the data is loaded into the in-memory database engine that powers the Data Model, rather than being placed in the cells of a worksheet.
This approach has several significant advantages. First, the Data Model's engine uses powerful compression algorithms, allowing you to work with datasets containing millions of rows, far beyond the one-million-row limit of a standard worksheet. Second, by loading directly to the model, you keep your workbook clean and focused on the analysis and visualization, rather than cluttering it with large raw data tables. This is the standard practice for any serious data modeling work in Excel.
Once you have loaded multiple tables into the Data Model, you need to tell Excel how they relate to each other. This is done in the Power Pivot window, which is the primary interface for managing the Data Model. A solid understanding of the Power Pivot environment is essential for the 77-428 Exam. Within Power Pivot, you can switch to the "Diagram View," which provides a graphical representation of all the tables in your model.
In the Diagram View, you can create relationships by simply dragging the key column from one table to the corresponding key column in another. For example, you would drag the "CustomerID" column from your Sales table to the "CustomerID" column in your Customers table. This creates a one-to-many relationship, which is the most common type. Establishing these relationships correctly is the crucial step that enables all the powerful, multi-table analysis that the Data Model makes possible.
The 77-428 Exam heavily tests your ability to add business logic and calculations to your Data Model. The formula language used for this is called Data Analysis Expressions, or DAX. DAX is not a replacement for standard Excel formulas; it is a separate language that works exclusively within the Data Model. It is used to create two main types of calculations: calculated columns and measures.
A calculated column is very similar to a formula column in a standard Excel table. It adds a new column to one of the tables in your Data Model, and the formula is evaluated for each row of that table. For example, you could create a calculated column in your Sales table to calculate the profit for each individual sales transaction by subtracting the cost from the sales amount. Calculated columns are useful for creating new attributes for your data.
While calculated columns are evaluated row by row, measures are used for aggregation. This is a critical distinction for the 77-428 Exam. A measure is a DAX formula that is designed to be used in the "Values" area of a PivotTable. It calculates a single value based on the context provided by the PivotTable's rows, columns, and filters. The most basic measures use simple aggregation functions like SUM, COUNT, AVERAGE, MIN, or MAX.
For example, you would create a "Total Sales" measure using the formula :=SUM(Sales[SalesAmount]). When you place this measure in a PivotTable, it will calculate the sum of the sales amount based on the current filter context. If the PivotTable row is showing product categories, the measure will calculate the total sales for each category. This ability to create explicit, reusable measures is a cornerstone of professional data modeling in Excel.
To begin your preparation for the 77-428 Exam, you must build a strong foundation in these core data modeling concepts. The Excel Data Model is the central pillar of the entire exam. Your first goal should be to become comfortable with the end-to-end process of getting data into the model. This means practicing with Power Query to connect to different types of data sources and perform common data cleaning operations.
Next, focus your efforts on the Power Pivot window. Practice loading data into the Data Model and creating relationships between tables in the Diagram View. Finally, begin your journey with DAX. Start by mastering the difference between a calculated column and a measure. Create several simple examples of each. This foundational knowledge is the prerequisite for tackling the more advanced business logic and visualization topics covered in the 77-428 Exam.
If there is one function you must master for the 77-428 Exam, it is CALCULATE. This is the most important and powerful function in the entire DAX language. While simple aggregation functions like SUM can only operate in the current filter context, CALCULATE gives you the power to modify that filter context before the calculation is performed. This allows you to create an incredibly wide range of dynamic and sophisticated business calculations.
The basic syntax of CALCULATE takes an expression (like a measure) as its first argument, followed by one or more filter arguments. For example, the measure CALCULATE([Total Sales], Products[Color] = "Red") will calculate the total sales, but only for products that are red, regardless of any other filters that might be applied in the PivotTable. This ability to manipulate the filter context is the key to unlocking the true analytical power of DAX, and it is a central theme of the 77-428 Exam.
To create more complex filter modifications within CALCULATE, you often use dedicated filter functions. The 77-428 Exam will expect you to be familiar with the most important ones. The FILTER function allows you to create a filter based on a complex condition that is evaluated over a table. For example, you could use FILTER to find all sales where the profit margin was above a certain percentage.
The ALL function is used to remove or ignore existing filters. This is essential for calculating percentages. For example, to calculate the percentage of total sales for a specific product category, you would divide the sales for that category by the sales for ALL product categories. The ALLEXCEPT function is a convenient variation that removes filters from all columns in a table except for the ones you specify.
A very common requirement in business analysis is to perform time-based calculations, such as comparing sales to the same period last year or calculating a year-to-date total. The 77-428 Exam covers these "time intelligence" calculations. The absolute prerequisite for any time intelligence in DAX is to have a dedicated Date or Calendar table in your Data Model. This table should contain a continuous sequence of dates and be marked as a "Date Table" in Power Pivot.
Once you have a proper date table, you can use DAX's powerful built-in time intelligence functions. Functions like TOTALYTD make it easy to calculate a year-to-date sum. SAMEPERIODLASTYEAR allows you to retrieve the value of a measure from the equivalent period in the previous year, which is essential for growth calculations. DATEADD is a flexible function that lets you shift a date range forward or backward by a specified interval (days, months, or years).
A key concept that the 77-428 Exam will test is the difference between standard aggregation functions and iterator functions. A simple aggregator like SUM works on a single column. An iterator function, which typically ends in "X" like SUMX or AVERAGEX, works by iterating through a table, one row at a time. For each row, it performs a calculation that you specify, and then, after it has finished iterating, it aggregates the results of those individual calculations.
This is extremely powerful for scenarios where you need to perform a calculation before you aggregate. A classic example is calculating total revenue. If you have a Quantity column and a Price column in your Sales table, you cannot simply sum the quantities and sum the prices. Instead, you must use an iterator like SUMX to go through the Sales table row by row, multiply the quantity by the price for each row, and then sum up those individual results.
To truly master DAX for the 77-428 Exam, you must understand the concept of evaluation contexts. There are two main types of context in which a DAX formula is calculated: the filter context and the row context. The filter context is the set of active filters that are applied to the Data Model. This is typically created by the rows, columns, and filters of a PivotTable or by the arguments you provide to the CALCULATE function. All simple measures are evaluated in a filter context.
A row context, on the other hand, exists when a formula is iterating through a table, one row at a time. This happens in a calculated column or inside an iterator function like SUMX. In a row context, the formula can refer to the values of any other column in the current row. A more advanced concept is "context transition," where a row context can be converted into a filter context, which is a powerful mechanism used within the CALCULATE function.
The 77-428 Exam covers the creation of Key Performance Indicators, or KPIs, within the Power Pivot environment. A KPI is a visual measure of performance that is designed to help you quickly assess whether you are meeting a specific business goal. In Power Pivot, a KPI is built on top of an existing base measure. To create a KPI, you define the base measure (e.g., Total Sales), a target value (which can be another measure or an absolute value), and a set of status thresholds.
For example, you could create a KPI for sales performance where the status is "good" (green) if you are at 100% or more of the target, "okay" (yellow) if you are between 80% and 100%, and "poor" (red) if you are below 80%. When you add this KPI to a PivotTable, it will display a graphical icon (like a traffic light or a check mark) next to the value, providing an instant visual cue about the performance.
Beyond the basics, the 77-428 Exam will expect you to be familiar with some more advanced DAX patterns. One of the most common is calculating ratios and percentages, such as a product's contribution to the total sales. This is typically done by creating a measure for the numerator (e.g., sales for the current product) and another measure for the denominator that uses the ALL function to calculate the grand total. The final measure then simply divides the numerator by the denominator.
A more recent addition to the DAX language that improves both the readability and performance of complex formulas is the use of variables. You can declare a variable using the VAR keyword, store the result of a calculation in it, and then reuse that variable multiple times within the same measure. This is much more efficient than calculating the same complex expression over and over again.
DAX is the calculation engine of the Data Model and is arguably the most challenging part of the 77-428 Exam. Your preparation must include extensive hands-on practice. The single most important function to master is CALCULATE. You should be able to confidently use it with various filter arguments and filter functions like ALL and FILTER. A deep understanding of evaluation contexts (row vs. filter) is what separates a novice DAX user from an expert.
Spend time building a proper date table and practicing the common time intelligence calculations like YTD and comparison with the previous year. Finally, be sure you understand the use case for iterator functions like SUMX and how they differ from their simpler counterparts. The ability to write and debug these advanced DAX formulas is a core competency that the 77-428 Exam is designed to validate.
Once you have built a robust Data Model and enriched it with DAX measures, the next step is to visualize and analyze the data. The 77-428 Exam heavily emphasizes the use of PivotTables for this purpose. Creating a PivotTable based on the Data Model is a significantly more powerful experience than using a traditional PivotTable. When you create the PivotTable, you will see all the tables from your Data Model in the PivotTable Fields list, not just a single list of fields.
The true power comes from the relationships you created. You can now build a single PivotTable that combines fields from multiple tables seamlessly. For example, you can place the "Product Category" field from your Products table on the rows, the "Country" field from your Customers table on the columns, and your "Total Sales" measure from your Sales table in the values area. The Data Model's relationships allow the PivotTable to automatically aggregate the data correctly.
A PivotChart is a graphical representation of the data in a corresponding PivotTable. It provides a dynamic and visual way to analyze your data, and the 77-428 Exam requires you to be proficient in creating and formatting them. When you create a PivotChart from a PivotTable that is based on the Data Model, any changes you make to the PivotTable (like adding or removing fields) are instantly reflected in the chart, and vice versa.
You can create all the standard chart types, such as column, bar, line, and pie charts, to visualize the results of your DAX measures. A key feature for creating interactive reports is the ability to use slicers and timelines. These graphical filters can be connected to both the PivotTable and the PivotChart, allowing users to easily slice and dice the data and see the chart update in real time.
Slicers and Timelines are essential tools for creating user-friendly and interactive dashboards, and they are a key topic for the 77-428 Exam. Slicers are large, graphical buttons that act as filters. For example, instead of using the traditional filter drop-down, you can create a slicer for "Product Category" that displays a button for each category. Users can then simply click a button to filter the report.
A Timeline is a special type of slicer that is designed specifically for filtering by date fields. It provides a visual timeline that users can interact with to filter the data for a specific year, quarter, month, or day. The most powerful feature of both slicers and timelines is the ability to connect them to multiple PivotTables and PivotCharts. This allows a single click on a slicer to filter an entire dashboard of visualizations simultaneously.
In addition to PivotTables and PivotCharts, Excel 2013 introduced a powerful new visualization tool called Power View. The 77-428 Exam will expect you to have a foundational knowledge of this tool. Power View is a highly interactive data exploration and reporting environment that is designed for creating visually stunning, presentation-ready reports. You create a Power View report on its own dedicated sheet, and it connects directly to your Data Model.
Power View provides a drag-and-drop canvas where you can create a variety of visualizations, including tables, matrices, cards, and a wide range of chart types like bar, column, scatter, and pie charts. The key feature of Power View is its interactivity. All the visualizations on a Power View sheet are interconnected. Clicking on a bar in one chart will automatically filter and highlight all the other charts and tables on the sheet, providing a fluid and intuitive data exploration experience.
Beyond the basic charts, Power View offers several advanced features that you should be aware of for the 77-428 Exam. One of the most visually impressive features is the ability to use "tiles." You can add a field to the "Tile By" area, and Power View will create a "trellis" or "small multiples" view, where it generates a separate version of your chart for each value in the tiling field. This is a very effective way to compare trends across different categories.
You can also add filters to your Power View report. You can apply a filter to the entire report sheet or to just a single visualization. A particularly powerful feature is the ability to create hierarchies in your Data Model. For example, you can create a hierarchy of "Category" and "Subcategory" in your Products table. When you use this hierarchy in a Power View chart, it will automatically enable drill-down and drill-up capabilities for the user.
Another new visualization tool introduced in this era, and a topic for the 77-428 Exam, is Power Map. Power Map is a three-dimensional geospatial data visualization tool that allows you to plot geographic data on a 3D globe or a flat map. If your Data Model contains geographic information, such as country, state, city names, or specific latitude and longitude coordinates, you can use Power Map to create rich, map-based visualizations.
You can visualize your data on the map in several ways, such as using columns, bubble charts, or heat maps. A key feature of Power Map is its ability to visualize data over time. If your data includes a time dimension, you can create an animated "tour" that shows how the data changes and moves across the map over time. This is a very powerful tool for analyzing geographic trends and patterns.
The ultimate goal of all this data modeling and visualization work is to build a cohesive and effective dashboard. The 77-428 Exam is designed to test your ability to bring all these different elements together to tell a clear story with your data. A good dashboard follows key design principles: it should be clear, simple, and relevant to the audience. It should present the most important information at a glance, with the ability to drill down for more detail.
In Excel, a dashboard is typically constructed on a single worksheet. You would arrange your most important PivotTables and PivotCharts in a logical layout. You would then add slicers and timelines and connect them to all the objects on the sheet to provide interactivity. You might even include a static image of a Power View or Power Map visualization. Using good formatting and layout techniques is the final step in creating a professional dashboard.
For the visualization section of the 77-428 Exam, your preparation should be highly practical. You must be comfortable creating PivotTables and PivotCharts that are based on the Data Model and use fields from multiple related tables. The most important skill to master here is the use of slicers and timelines. Practice creating them and, critically, using the "Report Connections" option to link a single slicer to several different PivotTables to create an interactive dashboard experience.
While you may not need to be a deep expert in Power View and Power Map, you should be able to perform the fundamental tasks. Practice creating a new Power View sheet, adding a few different visualizations, and applying a filter. Similarly, practice launching Power Map and plotting some simple geographic data. The ability to use all these tools to build a basic interactive report is a core competency for the 77-428 Exam.
While the business intelligence tools are the main focus of the 77-428 Exam, it also covers several other classic "expert-level" features. One of these is the Inquire add-in. The Inquire add-in is a powerful tool for auditing and analyzing complex workbooks to understand their structure and identify potential errors. It is particularly useful for workbooks with many complex formulas, links to other files, or a long history of modifications by different users.
The Inquire add-in provides several key capabilities. The Workbook Analysis report gives you a comprehensive overview of the workbook's structure, formulas, and potential issues like inconsistent formulas or hidden cells. You can create interactive diagrams that show the dependencies between cells, worksheets, or even different workbooks. One of its most powerful features is the ability to compare two versions of a workbook, which highlights every single change that has been made down to the cell level.
The 77-428 Exam will expect you to be proficient with Excel's suite of What-If Analysis tools. These tools are designed to help you explore different outcomes by changing the input values in your models. The first tool is Goal Seek. Goal Seek is used when you know the desired result of a formula but do not know the input value needed to achieve that result. You provide the target value, and Goal Seek will find the required input.
Scenarios are used when you have multiple sets of input values that you want to save and compare. For example, you could create "Best Case," "Worst Case," and "Most Likely" scenarios for a financial model. The Scenario Manager allows you to easily switch between these different sets of inputs. Data Tables are used to see how changes in one or two input variables affect the results of multiple formulas, displaying all the possible outcomes in a grid.
Solver is the most advanced What-If Analysis tool in Excel and a key topic for the 77-428 Exam. While Goal Seek can find an input for a single target, Solver is a full-fledged optimization tool that can be used to find the optimal solution for a problem with multiple variables and constraints. It is used to solve complex business problems like finding the product mix that will maximize profit or determining the shipping schedule that will minimize costs.
Setting up a Solver problem involves three steps. First, you define your objective cell, which is the cell you want to maximize, minimize, or set to a specific value. Second, you specify the changing variable cells, which are the input cells that Solver is allowed to adjust. Finally, you define a set of constraints, which are rules that limit the values of the changing cells (e.g., a variable must be an integer or must be greater than zero).
The 77-428 Exam covers several techniques for managing and consolidating data from multiple sources without using the full Power Query and Data Model stack. The Consolidate feature allows you to combine data from several different ranges into a single summary report. For example, you could take sales data from separate worksheets for different regions and create a consolidated table that sums up the sales for each product across all regions. This can be done by position (if the data is in the same layout) or by category (if the layouts differ).
You will also need to know how to work with links to external workbooks. This allows you to create a formula in one workbook that references a cell or range in another workbook. A key part of this is knowing how to use the "Edit Links" dialog to manage these external connections, such as checking their status, updating the values, or breaking the link if it is no longer needed.
While the 77-428 Exam is not a test of your ability to memorize hundreds of functions, it does expect you to be comfortable with some of the more advanced and commonly used ones, particularly in the financial and logical categories. You should be familiar with the core financial functions used for loan and investment calculations, such as PMT (to calculate a loan payment), PV (to find the present value of an investment), and FV (to find the future value of an investment).
In the logical category, you should be proficient with more than just a simple IF statement. Be prepared to use the IFERROR function, which is a clean and efficient way to handle potential errors in your formulas. You should also be comfortable with creating nested IF statements and combining them with other logical functions like AND and OR to build more complex conditional logic.
A hallmark of an Excel expert is the ability to customize the application's environment to suit their workflow and to manage important security settings. The 77-428 Exam includes objectives related to managing and configuring Excel options. You should be familiar with the key settings in the Excel Options dialog, such as how to change the default number of worksheets in a new workbook, how to configure AutoCorrect and AutoRecover settings, and how to manage language and proofing tools.
A particularly important area is macro security. You must understand the different levels of macro security and how to set them to protect yourself from potentially harmful code while still allowing trusted macros to run. You should also know how to customize the user interface, including how to add your most frequently used commands to the Quick Access Toolbar and how to create your own custom tabs and groups on the Ribbon.
While the business intelligence tools (Power Query, Power Pivot, Power View) are the heart of the 77-428 Exam, you cannot afford to neglect these other advanced features. Dedicate specific study time to the What-If Analysis tools. The best way to learn them is to create practical examples. Build a simple financial model and then use Scenarios and Data Tables to explore different outcomes. Set up a simple optimization problem and practice using Solver to find the solution.
For the Inquire add-in, the key is to understand its purpose as an auditing tool. You do not need to know every single feature, but you should be able to explain what it is used for. Finally, review some of the more advanced financial and logical functions to ensure you are comfortable with their syntax and application. A well-rounded knowledge of all these expert-level features is necessary for success on the 77-428 Exam.
In the final stage of your preparation for the 77-428 Exam, your first step should be to revisit the official Microsoft exam objectives. These objectives are the blueprint for the test and provide a detailed list of the skills that will be measured. The main objective domains are "Manage and Share Workbooks," "Apply Custom Formats and Layouts," "Create Advanced Formulas," and "Create Advanced Charts and Tables." Map the knowledge you have gained to these specific domains.
This final review will help you identify any areas where you still feel weak. For example, you may find that you are very confident in creating advanced charts (PivotCharts, Power View) but less confident in managing workbook options and security. Use this self-assessment to target your final study sessions, ensuring you have a solid understanding of every skill listed in the official guide for the 77-428 Exam.
A key part of your final review should be to consolidate your understanding of how all the different Excel business intelligence tools work together as a cohesive stack. This is a central theme of the 77-428 Exam. You should be able to describe the end-to-end workflow in your own words. The process starts with Power Query, which is used to extract data from various sources and transform it into a clean, usable format.
The clean data is then loaded into the Power Pivot Data Model. In Power Pivot, you create relationships between the tables and use the DAX language to add calculated columns and powerful aggregate measures that encapsulate your business logic. Finally, this rich, centralized Data Model becomes the single source of truth for all your visualizations, which you build using PivotTables, PivotCharts, Power View, and Power Map.
The 77-428 Exam, like other MOS exams, uses a live, project-based format. This is very different from a standard multiple-choice test. At the start of the exam, you will be provided with one or more starting Excel workbooks. You will then be given a series of tasks to complete within this simulated Excel environment. Each task will require you to use your practical skills to modify the workbook and achieve a specific outcome.
It is crucial to read the instructions for each task very carefully, as small details matter. Often, the tasks are sequential, meaning that a task later in the project may depend on you having correctly completed an earlier task. Therefore, it is generally not a good idea to skip tasks unless you are completely stuck. Managing your time effectively across the entire project is key to completing all the required steps.
As you review, pay special attention to common areas of confusion that often trip up candidates on the 77-428 Exam. One of the most frequent mistakes is confusing the use cases for calculated columns versus measures in DAX. Remember: calculated columns are for row-level attributes, while measures are for aggregations. Another common oversight is forgetting to mark your date table as a "Date Table" in Power Pivot, which is a prerequisite for all time intelligence functions to work correctly.
You should also have a clear mental model of how relationships work and how filters propagate from the "one" side to the "many" side. Finally, be absolutely certain you understand the difference between loading data from Power Query to a worksheet versus loading it directly into the Data Model. These conceptual distinctions are often the basis for tasks in the 77-428 Exam.
For a practical, project-based test like the 77-428 Exam, there is no substitute for hands-on practice. Reading about the features is not enough; you must have the "muscle memory" of actually performing the tasks in the Excel interface. The most effective way to prepare is to use a high-quality practice test software, such as GMetrix, which is an official practice test provider for MOS exams.
This type of software accurately simulates the live exam environment. It provides you with sample projects and a series of tasks to complete, just like the real exam. Working through these practice projects will build your speed, accuracy, and confidence. It will also help you get used to the specific wording and format of the tasks, which is a critical part of being prepared for the 77-428 Exam.
When you take the 77-428 Exam, you will be working in a simulated Excel environment. Be prepared for it to feel slightly different from your day-to-day use of the software. The exam interface will have a window with the task instructions and a live Excel workbook. You will need to read the instructions and then perform the required actions in the workbook. The interface will include buttons to move to the next task, mark a task for review, or even reset the project if you make a major mistake.
Use the "Skip Task" button strategically. If you read a task and have absolutely no idea how to do it, it may be better to skip it and move on to ensure you have enough time for the tasks you do know how to complete. The key is to stay calm, read carefully, and trust the hands-on practice you have put in.
Earning the Microsoft Office Specialist: Excel Expert certification by passing both the 77-427 and 77-428 exams is a major accomplishment. It is a credential that is recognized and respected by employers worldwide as a definitive validation of your high-level skills in data analysis and modeling. It proves that you can handle complex data challenges and can leverage Excel's most powerful features to provide valuable business insights.
