PBIXRay

PBIXRay is an open source Python library for inspecting `.pbix` files outside of Power BI Desktop. Because they share the same underlying engine, PowerPivot models from Excel `.xlsx` workbooks and Analysis Services backups (`.abf`) are supported through the same API. This site brings together the library docs, hands-on examples, and deep technical articles on the PBIX file format for Power BI developers.
