About the CSV to CSV format

Values are deterministic-ish patterns for demos — not cryptographically random identities.

  • QA datasets
  • UI demos
  • Load-test seeds

How to use this tool

  2. Set options if shown, then run the tool.
  3. Copy or download the result.

Tips for best results

  • Do not treat mock emails as real contacts.
