About this tool
Validate UUID strings when debugging IDs from APIs, logs, and data imports. Check the version and variant without switching to a separate script.
UUID Validator is meant for the opposite job: checking IDs that already exist in logs, APIs, spreadsheets, or imported files. It helps confirm whether a value is really a UUID and whether the version and variant match expectations before the value moves further through a workflow.
- Validates one or many UUID strings line by line.
- Shows whether each value matches the expected RFC variant.
- Highlights the detected UUID version for quick inspection.
How to use UUID Validator
Paste one or many UUID strings, review the validation result for each line, and use the version details to spot malformed or unexpected IDs quickly. For bulk checks, test representative samples first so you can catch formatting drift before auditing a larger import or dataset.
