How it works

- Export as JSON array, CSV, or formatted table text.
- All generation happens locally — no network requests, no data leaving your browser.
A fake data generator (or test data generator) creates realistic, randomised data for use in software development and testing. When building applications, you need sample data to populate databases, test UI components, develop API endpoints, and write unit tests — but using real customer or user data for this purpose is a privacy risk and often illegal. Fake data generators produce plausible names, email addresses, phone numbers, addresses, dates, and other field types that look real but are entirely fabricated.
