Is the generated data safe to use on public sites?

Yes! All names, addresses, emails, and company names are randomly stitched together by an algorithm. While they read like real data, they are entirely fictional.

How many rows can I generate at once?

You can generate up to 1,000 rows at a time. Because it runs client-side, keeping the limit at 1,000 ensures your browser remains responsive while generating the data.

Can I use this offline?

Once the page has loaded, the generation happens entirely in your browser using JavaScript. If you lose internet connection after loading the page, you can still generate new data!
