Is valid UUID

Checks if the value is a UUID string, optionally of specific versions.

Checks whether the incoming value is a UUID, the long unique identifier written as five groups of hexadecimal characters separated by dashes, such as f47ac10b-58cc-4372-a567-0e02b2c3d479. Use this to confirm an identifier field holds a properly shaped UUID before you use it as a key or pass it to another system, or to route records with a missing or malformed identifier down a different path.

Upper and lower case are both accepted. Only text can be a UUID: numbers, on/off values, empty values and lists never match. If you would rather be alerted when a field holds the wrong kind of value, turn on Throw error when data type is not string.

Fields

Sample data

This checks each entity’s id field.

With Versions left empty, any value in UUID format matches:

Incoming value	Result
f47ac10b-58cc-4372-a567-0e02b2c3d479	Matches
F47AC10B-58CC-4372-A567-0E02B2C3D479 (upper case)	Matches
00000000-0000-0000-0000-000000000000 (NIL)	Matches
f47ac10b-58cc-9372-a567-0e02b2c3d479 (a version not defined yet)	Matches
f47ac10b58cc4372a5670e02b2c3d479 (no dashes)	Does not match
order-1001	Does not match
12345 (a number)	Does not match
null (no value)	Does not match

With Versions set to V4 and V7, only those versions match:

Incoming value	Result
f47ac10b-58cc-4372-a567-0e02b2c3d479 (V4)	Matches
018a7c2c-4b68-71f2-8000-062828b8493d (V7)	Matches
00000000-0000-0000-0000-000000000000 (NIL)	Does not match
