FAQ
Does this identify the UUID version too?
This version focuses on format validation and normalization rather than detailed version breakdown.
Can I use it with exported IDs?
Yes. It is useful when you need a quick pass on IDs copied from logs, CSVs, or app screens.
How it works
Paste a UUID to verify its format and get a normalized lowercase version when the value is valid. The result is produced immediately so you can review it before copying or using it elsewhere.
Privacy
