What it does
You point Claude at a spreadsheet of companies or contacts, and Claude standardizes names and domains, checks emails and phone numbers, and flags bad rows without deleting anything. Your original file is kept untouched in a separate folder. You get a cleaned, validated version ready for enrichment or import.
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?
Some. To get the most from this one you may need to be comfortable with code, the command line or technical setup.
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 edits files you point it at; run through Claude Code or a similar terminal-based setup.
As with any add-on, only install skills from sources you trust, and read what it does first.
