[Introduction]

Starting January 25, 2026, all new reports created in the Power BI service will use the Power BI Enhanced Report format (PBIR) by default. Existing reports will automatically convert to PBIR when edited and saved. Power BI Desktop will adopt PBIR as the default format with the March 2026 release.

The PBIR format is designed to improve source control compatibility and enable modern development practices such as continuous integration and continuous delivery (CI/CD). It also supports collaborative development and allows AI agents and scripts to programmatically create, edit, and manage Power BI reports. Learn more in the PBIR documentation.

[When this will happen:]

January 25, 2026

[How this affects your organization:]

• Who is affected: Power BI developers using the Power BI Project (PBIP) file format and Fabric Git integration.
• What will happen:
  

  • Report metadata will now be saved in PBIR format, replacing the previous PBIR-Legacy format that relied on a single JSON file.
  • PBIR is more compatible with source control systems, improving versioning and collaboration.
  • Users working with PBIX files will not see changes in their workflow, but report metadata inside PBIX will also use PBIR.
  • PBIR remains in Preview; this update makes PBIR the default before general availability (planned for later in 2026).
  • Admins can opt out during the Preview by disabling the tenant setting: “Automatically convert and store reports in the Power BI enhanced metadata format (PBIR).”

[What you can do to prepare:]

• No immediate action is required unless you want to opt out.
• If opting out, disable the Admin Tenant Setting in the Power BI Admin portal.
• Review internal documentation and update any references to report metadata formats.
• Communicate this change to your Power BI development teams.
