Checking UUID Strings Before Using Them in Applications

UUID values are commonly used as identifiers in databases, APIs, logs, distributed systems, test data, and application records. A small formatting mistake can make a UUID fail validation or cause issues when it is used in code, queries, or request payloads.

This UUID Validator helps you validate UUID format, check whether a UUID string is valid, detect the UUID version, and inspect multiple UUID values directly in your browser.

Validating UUID Format in the Browser

  1. Paste one UUID or multiple UUID values into the input box.
  2. Click Validate UUID.
  3. Review whether each UUID value is valid or invalid.
  4. Check the UUID version and variant when available.

Common UUID Validator Use Cases

  • Checking UUID values before using them in API requests.
  • Validating database IDs copied from logs or queries.
  • Reviewing generated UUIDs before storing test data.
  • Detecting UUID versions such as UUID v1, v3, v4, or v5.
  • Finding invalid UUID strings in copied lists.

Frequently Asked Questions

What does a UUID validator check?

A UUID validator checks whether a UUID string follows a valid UUID format. It can also identify the UUID version when the value includes a standard version marker.

Can this tool validate multiple UUIDs?

Yes. You can paste multiple UUID values separated by lines, spaces, or commas and validate them together.

What UUID versions can be detected?

This tool can detect common UUID versions from the UUID string, including version 1, version 3, version 4, and version 5 when the UUID is in standard format.

Is my UUID data uploaded to a server?

No. UUID validation happens directly in your browser. Your UUID values are not uploaded to a server.
