Fake Data Generator

Fake Data Generator

Build a schema, pick a row count, and generate realistic placeholder data as JSON, CSV, or a table — all computed locally in your browser.

Schema

Safe by design

  • Emails only use @example.com / .org / .net — reserved domains that can never be real addresses.
  • Phone numbers use the fictional (555) 01X-XXXX range.
  • Credit cards use well-known test card bins — for testing only, never real.

Reproducible data with seeds

        

          Enter a seed and the generator switches to a deterministic PRNG (mulberry32),
          so the same schema, row count, and seed always produce identical output — handy
          for snapshot tests and bug reports. Leave the seed empty for fresh, random data
          on every generate.
