About Test Data Generator
Toggle the fields you need and choose a row count, then the generator produces a table of realistic-looking data instantly. Supported fields include names, email addresses, phone numbers, cities, countries, companies, UUIDs, dates, booleans, integers, colors, and avatar initials.
Preview the result as a table, copy it as JSON, or download CSV or JSON files for seeding databases, testing APIs, or filling forms during development.
Generation runs entirely in your browser - nothing is uploaded, stored, or sent to a server. Re-generating produces a fresh random set every time.
