Frequently Asked Questions
What do I get?
An LLM-ready prompt containing your complete model structure: tables, columns with data types, measures with full DAX expressions, relationships, M code, data sources, and report pages. Copy it into Claude or ChatGPT to document, optimize, or troubleshoot your model.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.Is my data safe?
Yes. We extract structural metadata only - table names, column definitions, query steps, DAX expressions. Your actual data values are never accessed or transmitted. 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?
Your file is sent to our API for processing, where we extract metadata only - table names, column definitions, DAX expressions, M code. Your actual data values are never read or stored. The file is processed in memory and immediately discarded. For formal audit evidence with signed Evidence Packs, 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.
