Spreadsheet review tools

A browser extension and local service for finding suspicious formulas and reviewing corrections.

Fictional demonstration workbook. The public project is not a client reporting environment.

The problem

A report can balance while its formulas, source links, or mappings are still wrong.

What I built

I built a Chrome extension and Python service to flag formula and link issues, explain findings, and ask before changing a cell. The service preserves the prior value and restores it if verification fails.

What you can inspect

The repository contains the detector and extension tests. Findings that require accounting judgment remain with the reviewer.
