If you've been working with Power BI for a while, you're used to .pbix files. They work, but they come with a significant limitation: they're binary blobs. You can't diff them, you can't merge them, and you definitely can't put them through a proper CI/CD pipeline.
That's where PBIP (Power BI Project) comes in.
What is PBIP?
PBIP is Microsoft's text-based project format for Power BI. Instead of a single binary .pbix file, your report is broken into a folder structure containing human-readable files:
My Report/
├── My Report.pbip
├── definition/
│ ├── report.json
│ ├── pages/
│ │ ├── page1/
│ │ │ ├── page.json
│ │ │ └── visuals/
│ │ │ ├── visual1/
│ │ │ │ └── visual.json
│ │ │ └── visual2/
│ │ │ └── visual.json
│ │ └── page2/
│ │ └── ...
├── My Report.SemanticModel/
│ ├── definition/
│ │ ├── model.tmdl
│ │ ├── tables/
│ │ │ ├── Sales.tmdl
│ │ │ └── Date.tmdl
│ │ └── relationships.tmdl
Every visual, every DAX measure, every relationship is a separate text file. This changes everything.
Why does this matter?
1. Version control finally works
You can commit your Power BI report to Git. When you change a single measure, the diff shows exactly what changed — not "binary file differs". Code reviews for Power BI become possible.
2. CI/CD pipelines
With text files, you can build automated pipelines that validate your reports, check for broken references, and deploy across environments. This is real DevOps for Power BI.
3. Automation tools can process your reports
Tools like Dummy BI Automate read PBIP folders to extract metadata, switch datasources, and generate documentation. None of this is practical with binary .pbix files — although Dummy BI Automate can also open .pbix files directly via a built-in converter if you can't switch to PBIP yet.
4. Collaboration with fewer conflicts
Multiple developers can work on different tables or measures in the same report with significantly fewer merge conflicts than with .pbix. Conflicts can still happen — for example, when two people edit visuals on the same report page — but they're manageable text conflicts rather than binary dead ends.
PBIP vs PBIR
You might also hear about PBIR (Power BI Report), which is the newer evolution of the report definition format within PBIP. PBIR uses individual JSON files per visual instead of a single report.json — the folder structure shown above is the PBIR layout. Older PBIP projects may have a single report.json instead of separate pages/ folders. Dummy BI Automate supports both the legacy PBIP format and the newer PBIR format.
Note: PBIP is now the default save format in recent versions of Power BI Desktop. If you haven't switched yet, Microsoft is clearly signalling that PBIP is the future.
Getting started with PBIP
- Open Power BI Desktop
- Go to File → Save as and choose Power BI Project (.pbip)
- Your report is now a folder of text files
- Initialize a Git repository in that folder
Once you have your report in PBIP format, you can use Dummy BI Automate to document it (25+ metadata sheets), switch its datasource, or run a health check — all from the same project folder.
Even if you can't switch to PBIP yet, Dummy BI Automate can read .pbix files directly via a built-in converter.
The bottom line
PBIP is not just a file format — it's the foundation for treating Power BI development like real software engineering. If you're not using it yet, now is the time to start.
