When to use UUID Validator and Inspector
Use this inspector when a database identifier is rejected or when you need to distinguish UUID versions in an API response. Paste one canonical UUID per line. The report shows whether its shape is valid, its normalized spelling, version bits and variant. Nil and maximum UUIDs are identified separately because their reserved patterns do not describe ordinary generated identifiers.
How to interpret the result
A syntactically valid identifier is not proof that a generator used secure randomness or that the value is unique. Version seven identifiers include a millisecond timestamp that is shown as an ISO date when representable; other versions do not receive that interpretation. This tool accepts the standard hyphenated form only and reports invalid rows individually instead of silently discarding them.
