Considerations Before Changing the Data Source

Before switching to a new Excel file, keep the following in mind:

  • Column Headers Must Match: Ensure that the column names in the new file are identical to those in the original file.
  • Number of Columns Should Be the Same: The structure of both files must be identical to avoid errors.
  • File Location Consistency: If your Excel files are stored in different locations, ensure that Power BI has access to them.

 

Conclusion

Changing the data source in Power BI from one Excel file to another is a straightforward process if you maintain consistency in your data structure. Following these steps will help you seamlessly switch data sources while keeping your reports intact.
