Tips & use cases
  • Names, emails and cities in the same record belong to the same fictional person, so the data looks consistent.
  • Emails use the reserved example.com domains and phone numbers use the 555-01xx range, so nothing reaches a real inbox or phone.
  • Open the result in the Tree Viewer or convert it to CSV for spreadsheets.
