Usage guide and examples

Create independent identifiers

Choose UUID v1, v3, v4, v5 or v7, set 1–100 results and choose letter case. Results are generated on opening and when options change; Generate creates another batch. v3/v5 use DNS or URL namespaces and repeat for the same names and namespace. Click a row to copy one UUID, use the top-right button to copy all, or clear the results.

Check the input format and options with this example before using your own data. Random values, file sizes and presentation vary with the input and settings.
