📋 Abstract
The Power BI Fixer is an interactive development environment that runs natively inside Microsoft Fabric Notebooks. It combines Semantic Link, ipywidgets, and TOM (Tabular Object Model) to provide a comprehensive tool for scanning, exploring, fixing, and documenting Power BI reports and semantic models — all from a single notebook cell.
The Problem It Solves
Power BI developers face a fragmented workflow:
- Report issues (pie charts, missing data labels, page sizes) require manual visual-by-visual fixes in Power BI Desktop
- Model best practices (missing descriptions, floating point types, foreign key visibility) need Tabular Editor or manual scripting
- No single tool lets you scan a report AND its underlying model, see the results side-by-side, and fix everything in one workflow
- PBIR format adoption is slow because upgrade tooling is scattered
The PBI Fixer addresses all of these by providing 12+ interactive tabs, 17 report fixers, 25+ semantic model fixers, and a unified scan-and-fix workflow — running entirely in a Fabric Notebook.
~17,000 lines of new Python code across 5 UI & tab modules (9,439 lines — incl. Fix All, Model Explorer, Report Explorer, Prototype, Translations, Model Diagram, About), 15 report fixers (3,038 lines), 4 report helpers (593 lines), and 33 semantic model fixers (3,797 lines) — all written from scratch for this project.
