UUID / GUID Generator

Your version 4 UUID (GUID)

Generate another UUID

UUID (universally unique identifier) and GUID (globally unique identifier) are commonly used interchangeably. This tool generates an RFC 4122 version 4 UUID that can be used anywhere a GUID string is expected. (Note: some Microsoft APIs serialize a GUID's bytes in a different order, so the two aren't always byte-for-byte identical in binary form.)
