Power BI PBIX Auditor and Lineage Extractor
Audit Power BI PBIX files for model structure, DAX expressions, M code, data sources, and lineage. The export is LLM-ready and does not include report data values.Short answer: the PBIX auditor extracts Power BI model structure, DAX, M code, data sources, and lineage into a metadata-only export for review.
Your file is sent to the analysis API, processed in memory, and discarded after the response.
Your data stays private
Your file is sent to the analysis API, processed in memory, and discarded after the response. The extractor returns structural metadata such as table names, relationships, DAX, M code, and data-source references. Report data values are not returned or stored.FileMetadata onlyThe export describes structure, not report rows
ModelNo AI model processingDeterministic parsing handles the file
StorageNo file storageFiles are discarded after the response
ScopeReview readyClear enough for internal review
Frequently asked questions
What does the PBIX auditor extract?
The PBIX auditor extracts structural metadata from a Power BI file: tables, columns with data types, measures with full DAX expressions, relationships, Power Query M code, data sources, report pages, and authorship metadata. The export is built for documentation, optimization, or troubleshooting without report data values.What are DAX and M code?
DAX (Data Analysis Expressions) is Power BI's formula language for measures and calculated columns - similar to Excel formulas but more powerful. M code is the language behind Power Query that handles your data transformations. We extract both so LLMs can help you optimize or debug them.How does the extraction work?
A PBIX file is a ZIP archive. We open it and parse the internal files: DataMashup for Power Query M code, DataModelSchema for tables/measures/relationships, Report/Layout for pages and visuals, and docProps for authorship metadata. No AI models involved - just deterministic parsing of documented file formats.How is my file handled?
Your file is sent to our analysis API, processed in memory, and discarded after the response. The export contains structural metadata, not report data values. The analysis uses deterministic rules, not AI models.Why do you ask for my email?
We're a small team building tools for Power BI professionals. We may reach out to ask if the export was useful and get your feedback on what would make it better.Can I use this at work?
Use your organization's file-handling rules. The API extracts metadata such as table names, column definitions, DAX expressions, and M code, then discards the file after the response. For formal audit evidence with signed provenance records, see CMD+RVL Outcomes.PBIX files follow the Open Packaging Conventions (OPC) standard - the same ZIP-based format used by Office documents. This tool parses documented file structures; no reverse engineering required.
