UUID Generator

How this tool works

A UUID is a text identifier commonly used to distinguish records, test data, objects and resources in software projects. This tool creates a random UUID using the browser’s crypto.randomUUID function when the browser supports it.

How to use it

1. Choose Generate UUID to create a new identifier.
2. Use Copy to copy the displayed value.
3. Paste the identifier into your test data, local project or other intended field.

Example and practical tips

A UUID often looks like a group of hexadecimal characters separated by hyphens, for example 123e4567-e89b-12d3-a456-426614174000. That example illustrates the format; the generator creates a fresh value.

Generate a new value when you need a new identifier. A UUID is not a password and should not be treated as a substitute for access control, authentication or authorization checks. If Generate does not work in an older browser, try an up-to-date browser that supports crypto.randomUUID.
