Power BI Desktop Does Not Reflect JSON File Changes Without Reopening

[Sivapriya]

I'm working on an automation workflow that programmatically modifies Power BI project files (.pbip format), specifically the report layout JSON files  using a backend server process.

The Problem:
Every time my server writes changes to the .pbip JSON files (report layout, visuals, pages), Power BI Desktop does not pick up those changes automatically. I have to manually close and reopen the file to see the updates.

Current Workflow:
Server writes changes to .pbip JSON → Close Power BI Desktop → Reopen file → Changes now visible

Any guidance from the community or Microsoft team would be greatly appreciated.

I think PBI Desktop only reads the pbip JSON at open, and it does not watch for external changes, so the supported way is just to close and reopen the project after ur server writes the new JSON.

Hello  Power BI Desktop loads .pbip JSON/layout files into memory when the project opens and does not auto-detect external file changes.

So after your backend updates the JSON files, you must reopen the PBIP file to see the changes. Currently, there is no supported hot reload or live refresh feature for report layout JSON files.
