Question 1

Is this test data generator really free?

Accepted Answer

Yes — completely free, no signup, no row-cap nag. Build your columns, preview, and download up to 1,000 rows per file as CSV, JSON, or Excel (TSV). Everything runs in your browser; your data never touches our servers.

Question 2

What kind of data can I generate?

Accepted Answer

Over 100 types — names, emails, phone numbers, addresses, companies, job titles, dates, numbers and more, powered by faker. Pick a type per column and reorder columns however you like.

Question 3

Does my data leave my computer?

Accepted Answer

No. Generation happens entirely in your browser with no account and no upload. Nothing is stored or sent anywhere.

Question 4

How is this different from Mockaroo?

Accepted Answer

It's instant and signup-free, and it's built by Fillr — a Chrome extension that fills real web forms with data you control. Generate a file here, or install Fillr to fill a live signup/checkout/QA form with your own rows, one click.

Question 5

Can I use this data to fill a form automatically?

Accepted Answer

Yes — that's exactly what Fillr's free Chrome extension does. Save any form as a preset, set a rule per field, and fill it with generated or your own data in one click. The generator on this page is the same engine.
