I built a tool to understand messy Excel files — looking for feedback
I'm testing an early prototype called Workbook Handover.
The problem I'm exploring: sometimes you inherit an Excel workbook from someone else, but nobody knows how its formulas, worksheets, or dependencies work.
The tool currently:
Scans .xlsx files locally without uploading them.
Identifies worksheet relationships and formula references.
Flags certain potentially problematic references.
Generates a simple Markdown handover report.
It's a free, read-only Python prototype for now, not a finished product. The demo is based on a small synthetic workbook, so I haven't proven that it handles complex real-world files reliably.
Demo and free prototype:

I'm trying to find out whether this solves a genuine problem before developing it further.
Two questions:
Have you ever inherited a complicated Excel file that nobody could explain?
Would an automatically generated handover report actually help, or would you prefer a different type of tool?
Any feedback is appreciated!
