What this does

Uploads your spreadsheet, runs structural checks (formula errors, broken cross-sheet references, hidden data, external links), and returns a copy of the file with a _xlsx-for-ai tab explaining each finding — what we found, what's at risk, and how to fix it.

We don't store your file. Files are processed in memory and deleted within an hour.
