Pick the columns and how many rows, and get sample data as CSV or JSON to test an import, a table layout or a script. Email addresses are always on example.com, a domain reserved by the standards body precisely so that examples cannot reach anyone. Generators that use a plausible real domain end up sending test messages to a stranger’s mailbox the first time somebody wires the data into a live system.
This page loads no libraries at all — the work is done by the browser itself. Your file is read on your own machine and never sent anywhere — open your browser's network tab and watch while you use it.
It is reserved by RFC 2606 and cannot be registered by anyone, so nothing addressed there can arrive at a real person. Sample data has a way of escaping into staging systems and, occasionally, into production; when it does, the difference between a reserved domain and a plausible-looking real one is the difference between a harmless bounce and a stranger receiving your test emails.
name, email, city, number, id, date and bool are all understood, and anything else you name is filled with a simple placeholder rather than rejected — so a column list copied straight from your schema works without editing.
The values are drawn using the browser’s cryptographic randomness, so two runs differ. That is the opposite choice from the lorem ipsum generator, and for the opposite reason: placeholder prose should stay put so layouts stay comparable, while test rows should vary so a unique constraint or a sort order actually gets exercised.
They are surnames and first names of well-known figures from computing history, combined at random, so the combinations are not real people. They are recognisable enough to be obviously fake when they turn up somewhere they should not.
