A Chrome extension that anonymizes and redacts personally identifiable information (PII) from Excel/CSV files.
Think HR, payroll, or equity comp spreadsheets — cleaned in seconds.
100% local. Zero uploads. No creepy permissions. No PII, no cry.
Built by In the Money AI — the same nerds behind Izzie, your AI for equity and payroll.
- Zero network permissions — extension doesn’t even ask.
- 100% client-side — anonymization happens in your browser.
- No uploads, ever — your data never leaves your machine.
- Reversible mapping (optional) — CSV export shows exactly what got scrubbed and how.
- Audit-ready summary (optional) — JSON export documents detection details and version info.
Perfect for anonymizing files before sharing, demoing, audits, or running through AI tools. Handles:
- Employee names and IDs
- SSNs and tax IDs
- Emails and phone numbers
- Home addresses, DOBs
- Salary and comp data
- Equity grant and award info

- Audit-friendly outputs — summary JSON proves what was scrubbed and which version of Anon-Izzie did it.

- Fast + friendly UI — drag & drop, progress tracker, field-by-field selection, real-time logs.

- Go to
chrome://extensions/ - Enable Developer Mode
- Load unpacked → select project folder
- This tool is provided “as is.”
- Not legal, tax, or compliance advice — validate anonymized outputs before sharing.
- No anonymizer is perfect: check your file before you send it, and keep the mapping CSV private and secure if you plan to reverse.
- The original file is never modified, only a copy is generated.
🐿️ Fun fact: Anon-Izzie anonymizes spreadsheets, not your browser history.
🤖 She doesn’t talk to the cloud. She barely talks to her coworkers.
