Frequently asked questions
Is the data real?
No — it's randomly generated fake data for testing. Any resemblance to real people is coincidental.
Can I export to CSV?
Yes — switch the format to CSV for a spreadsheet-ready file, or use JSON for APIs and code.
Is anything uploaded?
No — data is generated entirely in your browser and never sent to a server.
How many rows can I generate?
Up to 200 rows at a time — generate again for more.
