💡 All data is randomly generated in your browser — no rows limit, no account, nothing uploaded. Names, companies, and addresses are fictional and any resemblance to real data is coincidental.

Paano ito Gumagana

Need realistic-looking test data to seed a database or build a UI? Many generators (like Mockaroo) cap the free tier at around 1,000 rows. This one runs in your browser with no limit.

1
You define your schema
Add fields and pick a type for each — names, emails, addresses, dates, numbers, booleans, UUIDs, custom lists, and more.
2
Rows are generated locally
Each row is built from curated, fictional data pools using your browser's random number generator. Nothing is sent to a server.
3
You export in your format
Output as JSON, CSV, SQL INSERT statements (with your table name), or NDJSON.
4
Copy or download
Copy the result to your clipboard or download it as a file, ready to seed a database or feed a test suite.

All data is fabricated and generated entirely on your device — there are no row limits, no sign-up, and nothing is uploaded. Perfect for seeding dev databases, prototyping UIs, and load-testing.
