• 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.

• Flexible modes — Contextual, Range, and Strict.
• Pick your downloads — anonymized file always included; mapping CSV and JSON summary are optional.
• Audit-friendly outputs — summary JSON proves what was scrubbed and which version of Anon-Izzie did it.

⚠️ Notes

• 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.
