UUID Validator
Validate UUID v1, v4, and v7 formats and check if a UUID string is properly formatted.
A string that looks roughly UUID-shaped, the right length with dashes in the right places, isn't necessarily a valid one, and even a properly formatted UUID still comes in different versions, v1 built from a timestamp and a MAC address, v4 purely random, v7 time-ordered, each identifiable by a specific version digit embedded in the string itself. This tool validates whether a UUID string is actually correctly formatted and identifies which version it is from that embedded digit, rather than just confirming it merely looks the right shape.

Useful for confirming a UUID pulled from a log or a database is actually valid before trusting it, identifying whether a given UUID is v1, v4, or v7 by reading its version marker, or catching a malformed UUID that's missing a dash or has an extra character before it causes an error somewhere else.
