Deprecation of old Excel and CSV import experience in Power BI Service

Excel and CSV files remain a valid data source for Power BI semantic models and reports. You can use them to create reports in the Power BI service from the Create page or in Power BI Desktop.

This blog post is for users who created reports using the old experience to import an Excel or CSV file from the Create page in the service. There's no impact for users who created semantic models in Power BI Desktop.

How to identify affected semantic models

Semantic models created by the old import files experience can't be edited in the browser or downloaded and have no options to schedule a refresh. If your semantic model can be edited in the browser, downloaded, or has a scheduled refresh option, you're already using the new Excel and CSV connectors, and there's no impact on your semantic model and reports.

What is changing?

Reports created using the old import Excel or CSV experience stop refreshing from their source file as of July 31, 2026. There's no workaround or fix to keep them updated. These reports need to be recreated to continue updating. For guidance on creating reports from Excel and CSV files, refer to Get data from Excel workbook files.

These reports can still be consumed and edited, even past this date, but the data no longer stays in sync with the source Excel file.

We're removing the old Excel and CSV import experience in Power BI service, which is currently accessible through the Create page, by May 31, 2026. The existing options for Excel and CSV, as well as Get data, continue to be available. We recommend you start using the other options for Excel and CSV files.

Key dates to remember

The legacy Excel and CSV import experience will be deprecated in phases: 
  • May 31, 2026: You will no longer be able to create new semantic models using the legacy import experience. 
  • July 31, 2026: Existing semantic models created with the legacy experience will stop refreshing. Reports based on these models will still open, but their data will no longer update. To keep your reports current, recreate them using a supported import method. 
  • August 31, 2026: Existing semantic models created with the legacy experience will no longer be available for querying. Reports bound to these semantic models will no longer open and will display an error message. 
For more details on identifying these semantic models and options to recreate your reports, refer to the Get data from Excel workbook files documentation.

Next steps

Thank you for being part of the Power BI community and for your continued feedback as we evolve the platform.
