How would you analyze Power BI reports data in Microsoft excel ?

Analyzing Power BI report data in Microsoft Excel is a multi-step process that involves connecting to the data source and working with it within Excel. Here's how you can achieve this:

1. Connect to Power BI Data:

There are two primary ways to connect Excel to Power BI data:

  • Analyze in Excel: Open the Power BI report you want to analyze. Click on "Export" and choose "Analyze in Excel." This will download an Excel workbook with a connection to the Power BI data model.

  • Get Data: In Excel, go to the "Data" tab and click "Get Data" > "From Power Platform" > "From Power BI." Select the workspace and report you want to connect to.

2. Explore and analyze the data:

Once connected, your Excel workbook will contain one or more tables holding the Power BI data. You can now analyze this data using the familiar Excel tools and functionalities:

  • PivotTables: Create PivotTables to summarize and analyze the data based on different dimensions and measures.

  • Charts and graphs: Generate various charts and graphs to visualize the trends and insights within the data.

  • Excel formulas: Utilize Excel formulas for calculations, manipulations, and further analysis of the data points.

  • Filters and slicers: Apply filters and slicers to focus on specific subsets of the data for targeted analysis.

3. Considerations and Limitations:

  • Live Refresh: Analyze in Excel creates a dynamic connection, allowing you to refresh the data directly from Power BI. However, Get Data creates a static snapshot of the data at the time of connection.

  • Data Model Complexity: Complex Power BI data models with multiple relationships or calculated columns might not translate perfectly into Excel, requiring adjustments or workarounds.

  • Collaboration and Version Control: Excel files are independent documents, making collaboration and version control for shared analysis challenging compared to the Power BI service.

Tips and Best Practices:

  • Filter before Exporting: If you know what specific data you want to analyze, apply filters in the Power BI report before using "Analyze in Excel" to avoid downloading unnecessary data.

  • Utilize Power BI Desktop features: If you need more advanced filtering or analysis capabilities, consider exporting the data model from Power BI to Power BI Desktop to prepare it for Excel analysis.

  • Document your steps: Clearly document the filters, connections, and transformations applied to the Power BI data in Excel to maintain transparency and reproducibility of your analysis.

Overall, analyzing Power BI data in Excel offers a familiar and flexible environment for manipulating and visualizing data for specific insights. However, be mindful of the limitations and consider the advantages of collaborative analysis within the Power BI service compared to standalone Excel files.
