03 / HOW TO USE
What this tool does.
A UUID is a fixed-format identifier that can help distinguish records, test fixtures, files or local development objects. This tool creates random version 4 values and keeps the result in this browser until you leave or replace it.
- Choose a quantity from 1 to 500.
- Select Generate, then copy the list or download a plain-text file.
- Use the IDs as identifiers only. UUIDs are not encryption and do not protect private data.
