Frequently asked questions
Is the data realistic enough for testing?
It is varied and correctly formatted. Emails use example.com and phone numbers use the reserved 555 range, so they never reach real people.
Is the Mock Data Generator free?
Yes. It is free with no sign-up, and it runs entirely in your browser, so your input is never uploaded or stored.
Is the output random every time?
Yes. Values are generated fresh on each run in your browser; nothing is stored, so copy or download what you need.
