UUID Sorter

Normalize UUID text and sort its canonical hexadecimal representation locally; UUIDv6/v7 naturally group by their leading time fields.

UUIDs — one per line

Order

Comparison

ReadyLexicographic UUID sorting is not universally chronological. UUIDv6/v7 place time fields first, while UUIDv4 is random.

Canonical or genuinely timestamp-aware

Timestamp-aware mode decodes only RFC-variant UUIDv1, v6, and v7. Non-time or unsupported rows remain explicit and follow the time-capable group rather than receiving fabricated timestamps.

RFC 9562 boundary

UUIDs are 128-bit values. Version meaning is interpreted only inside the appropriate variant, and representation conversion never changes the underlying 16 bytes.
