length (string) | Itential

The length (string) task counts the number of characters in a given string and returns the count.

The length of an empty string is 0.

Potential use case

This task specifies the maximum number of characters allowed for a string property. For example, to verify that a user provided exactly three characters (such as ATL, HNL, or LHR) for an airport code on an entry form, use length (string) to get the character count in the user-provided string. Additional logic applied elsewhere in the workflow can then compare that count to the acceptable value.
