What it does
You point Claude to a spreadsheet or a specific range of cells with messy data. It scans for issues like extra spaces, inconsistent capitalization, mismatched date formats, duplicate rows, and numbers stored as text, then proposes and applies fixes. You get a cleaned-up sheet ready for analysis.
Who it’s for
A good fit for people who work with spreadsheets and numbers and people who run the day-to-day of a business.
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
Edits spreadsheet files you point it at.
As with any add-on, only install skills from sources you trust, and read what it does first.
