UUID validator
Validate and normalize UUIDs (v1–v8) locally. Copy results or share a link.
Paste one or multiple UUIDs. The tool checks format, version, and variant, then outputs a normalized form. Runs locally (no upload).

Tip: “Share link” encodes your input/options in the URL hash (not sent to a server).
