About UUID generator

Create identifiers in UUID format for records or test data. Version 4 uses random data; version 7 includes a timestamp component for time-oriented ordering.

Steps, and limitations

How to use it

  1. Choose UUID v4 or UUID v7.
  2. Set the number of identifiers to generate.
  3. Generate the batch and copy or save the IDs.

Things to know

  • UUIDs are identifiers, not passwords or access-control tokens.
  • UUID v7 exposes approximate creation time. Check application support before changing an existing identifier format.
