Hello,
How can I get the length of a string in NWC Workflow. I see there is a Length function in NWC Forms, but I am looking for this in NWC Workflows.
Thank you.

May or may not work depending on the string your starting with.

Hi,
My approach would be to use a Regular expression to split the string up into a collection.
The config would look like this:
Then use a Count Items in collection action to count how many letters there are in the collection.
For some reason the count is always one more than required so just use a calculate a value action to subtract one.
Workflow would look like:
Export Key valid until this time on the 24th of October:

Thank you for this alternative solution, @SimonMuntz .
I tested your example and it works great for a single word. The string we want to check the length of could be any number of words, spaces and punctuation. What regex would you recommend for that situation?

Hi,
I think this regex would cover it.

Thank you @SimonMuntz
The regex [Ss] did indeed work with multiple words. And it even worked when I included a trailing space.
I think this solution is cleaner than one I previously marked as the answer.
My only concern with @SimonMuntz suggestion, and this may be unfounded, was if there was a max limit on a collections size. I have no idea if there is one - but if there is, that may be a limitation you run into with that solution.

Hi,
Collection do have a limit of 5000 objects.
So as long as the string is under 5k characters (which is a lot) my solution will work.
