UUID generator

Up to 10000

Bulk UUID generator

Make a batch of version 4 or version 7 UUIDs and download TXT, CSV, or JSON. The page shows the first 20 so a long list does not fill the screen. Nothing is uploaded.

Version

Use a whole number from 1 to 10000.

The preview lists the first 20. Copy all and the file downloads include every UUID in the batch.

Generation uses crypto.getRandomValues in this browser. Results are not uploaded. A new batch replaces the list.

Results 0

Choose a version and a count, then generate.

    TXT is one UUID per line. CSV has a header named uuid and then one UUID per row. JSON is an array of strings.

    Duplicates inside the batch are replaced. That check does not compare the batch with identifiers you already stored elsewhere.

    Questions

    How many can I generate?

    From 1 to 10000 in one batch. The page previews the first 20. Copy all and the file downloads include the full batch.

    Are the files uploaded?

    No. TXT, CSV, and JSON are created in the browser and downloaded to your computer.

    Which version should I pick?

    Use v4 for random identifiers. Use v7 when you want new values to sort near each other by millisecond. v7 on this page is still not a counter inside one millisecond.
