What it does
Tell Claude whether to check a selection, a sheet, or the whole workbook, and it scans for issues like broken formulas, hardcoded numbers, and mismatched ranges. For full financial models, it also checks things like balance sheet ties and cash consistency. You get a list of problems to fix before sharing the file.
Who it’s for
A good fit for people who work with spreadsheets and numbers and bookkeepers, finance teams and business owners.
Do you need to code?
No. You can use this without writing or editing any code.
How to install
Add it as a skill, or as part of its plugin. This skill also ships inside a plugin, so you can upload just this skill to Claude, or install the whole plugin it comes in. See the step-by-step guide.
Safety note
Reads and checks spreadsheet files you point it at.
As with any add-on, only install skills from sources you trust, and read what it does first.
