UUID Batch Generator
Create up to 1000 UUID v4 identifiers locally.
Create a small batch of version 4 UUIDs
How to use this tool
Enter an integer count from 1 to 1000 and run the tool. Each line receives a newly generated UUID from the browser cryptographic random source. Copy the lines into a staging dataset and confirm the receiving system expects the hyphenated UUID v4 format. A batch is helpful when you need sample IDs for imports or tests.
Check the result
UUIDs are identifiers, not secret credentials. The tool cannot guarantee that an external database accepts a particular row or format. Keep uniqueness constraints in your database, and do not treat possession of an ID as permission to access its record.

Frequently asked questions
Can I save my result?
Run the tool, then use its download control. Text results can be saved as a file; image and audio tools show their available export links after generation. A disabled download means a new result is needed.
Are my inputs uploaded?
The tool processes your input in this browser tab. Opening the page downloads the site assets; your tool inputs are not sent to a processing server. Save your result before closing the tab.
How do I start again?
Use Restore example to reset the editable fields, then run the tool again. Changing input invalidates the previous export so that you can generate a fresh result.
