Frequently asked questions

Is the generated data based on real people?

No — names, emails, and phone numbers are combined randomly from small built-in word lists, entirely in your browser. Any resemblance to real people is coincidental.

What is this useful for?

Seeding development databases, filling UI mockups, testing imports and APIs — anywhere you need realistic-looking JSON without touching production data.

How much data can I generate?

Up to 1,000 records at a time, with exactly the fields you select, ready to copy or download as JSON.
