UUID Validator

This tool validates RFC 4122 UUIDs by performing syntactic checks, version extraction, and variant verification. It accepts hyphenated (8-4-4-4-12) and compact (32-hex) forms, reports whether the input is valid, and returns a canonical, normalized representation when possible. The core output includes is_valid, version, variant, canonical_form, and a list of diagnostic errors to guide corrections. It is designed for integration into CI pipelines, data ingestion workflows, and log validation tasks.
Conceptually, the validator parses the string, enforces length and allowed characters, checks hyphen placement, reads the version nibble from the 3rd group, and examines the variant bits in the 4th group. It does not query any external system; it only uses the textual structure to determine validity. If valid, the tool outputs a canonical form with uppercase hex and standard hyphen positions.
Who benefits: software developers, QA testers, site reliability engineers, and data engineers; use cases include unit tests, ETL validation, log auditing, and API response validation.
Unique value: precise RFC 4122 validation with detailed diagnostics, deterministic outputs, and optional batch processing in higher tiers, plus normalization to a standard canonical form.
