About UUID Validator
UUID Validator is a simple developer utility for checking whether a value is a valid UUID and identifying its version. Paste a UUID from an API response, database record, log file, test fixture, configuration value or documentation example, and the tool checks the format locally in your browser. When the value is valid, it shows the UUID version so you can tell whether it is version 1, 3, 4, 5 or another valid variant. When the value is invalid, the result clearly explains that the format does not match the standard UUID pattern. This is useful for debugging integrations, validating imported data, reviewing identifiers, checking test payloads and confirming that generated values match expected structure. The tool does not upload or store the UUID you enter. It provides a copyable result summary and a clear button so you can validate multiple values quickly. The interface is intentionally clean and responsive, matching the rest of Toolexa’s utility pages.
