Frequently Asked Questions

Common questions about the free online test data table generator.

It builds rows of made up but realistic records that you can paste into tests, fixtures or database seeds instead of using real user data.
The seed decides the pseudo random sequence, so the same seed with the same columns and row count always rebuilds exactly the same rows.
You can mix id, name, email, date, price, status, boolean and number columns in one table and tick only the ones you need.
The table can be copied as comma separated CSV, as a JSON array of objects, or as a Markdown table ready for documentation.
They are pseudo random. Every row comes from a seeded mulberry32 generator, so results are repeatable rather than truly random.
No. Names, emails, prices and dates are invented, and every email address uses a reserved example domain that cannot deliver mail.
Yes. CSV and JSON both load into common importers, and in JSON mode booleans and numbers keep their real types instead of becoming text.
No. Every row is generated in your browser, so nothing you type and nothing you copy ever leaves your device.
The preview shows the first 25 rows to stay fast, while the copy box always holds exactly the row count you asked for.
You can generate between 1 and 500 rows per table, which keeps both the preview and the copied text comfortably fast.
