Frequently asked questions

Is it real data?

No. It is random combinations of sample names, surnames and words; emails use fictional companies.

Can I use it for SQL?

Yes. The SQL format produces an INSERT INTO statement with all rows and escapes single quotes.

How many rows can I generate?

Up to 1000 rows per generation.

Is anything sent to a server?

No. Data is generated in your browser.
