FAQ

Questions about the Bulk UUID Generator

How many UUIDs can I generate at once?

Up to 200 per click. Click Generate again for another fresh batch if you need more.

Are the UUIDs random enough for test fixtures and seed data?

Yes. They come from the browser crypto API (crypto.randomUUID or crypto.getRandomValues), so collisions are practically impossible.

How do I put bulk UUIDs into a SQL insert or CSV?

Copy the list, which has one UUID per line, and paste it into a spreadsheet column or wrap each line in quotes with your editor multi-cursor feature.

Is the Bulk UUID Generator free and private?

Yes. It is free, needs no sign-up and runs entirely in your browser, so what you type is not uploaded. You only sign in if you want to email a result to yourself or save it to your CareerByteCode profile.
