About the Fake Data Generator

Choose the fields you need and how many rows, and get test data that looks real enough to catch layout problems a row of "test test test" never would. Names, emails, phone numbers, addresses, job titles, dates, prices and identifiers are all available.

Each row is internally consistent, which matters more than it sounds. The name, email and username belong to the same person, and the city, region and postcode belong to the same country — so a row does not read as obviously assembled from parts. Emails use the domains RFC 2606 reserves so nothing can ever be delivered to one by accident. Output comes as JSON, CSV, SQL inserts or a JavaScript array.

Key features of the Fake Data Generator

Rows that hold together

The email derives from the name and the postcode from the country, so a record reads as one person rather than as assembled parts.

Realistic lengths

Names run from three characters to forty and some contain apostrophes — which is exactly what breaks a layout that looked fine with "test test test".

Undeliverable by design

Every address uses a domain RFC 2606 reserves, so nothing can reach a real mailbox even by accident.

Four output formats

JSON for a fixture, CSV for a spreadsheet, SQL for a seed script, or a JavaScript array to paste into a test.

Six locales

UK, US, German, French, Australian and Indian formats, each with the right postcode shape and phone pattern.

Frequently asked questions

No. Names are drawn from common lists and combined at random, and every email uses a domain reserved for documentation. Any resemblance to a real person is coincidence.
