What does UUID Validator do?
Validates a canonical UUID and reports its version. Paste your uuid on the left and NMSnabbit instantly shows the result on the right. For example, “550e8400-e29b-41d4-a716-446655440000” gives “Valid (v4)”. Everything runs locally in your browser — nothing is uploaded, so it stays private and works offline. You can process several values at once and copy the result with one click.
