Beta

Replace names, counterparties and other sensitive text in Excel and CSV files with tokens before sending them to an analyst. Runs entirely in your browser -- no upload, no backend, no third-party requests. Open source, Apache-2.0.

Highlights

  • xlsx, csv, tsv -- one file per run
  • Deterministic tokens (CUST-000007), not realistic fakes
  • The key that reverses masking never leaves your machine
