How to count characters on a string

Sometimes it's needed to count some characters on a string on a Nintex Workflow

This sample shows how to calculate it with 3 actions.

The used actions are:

I set a variable named myString with the value 123-1234-12345

Then I create the following variables

Firstly I count the total characters on my string using the action named "Convert Value"

Then I count the characters deleting the character you want to count ("-" (hyphen) in this case) , from the string

Then I use the action named "Math operation"

So you get the result on the variable named "myResult"

@fhunth does this show the character count 'live'? as the person is typing, or only once the form has been submitted?

I have a use for showing the number of characters typed into a cell / control whilst the person is typing it in, is that possible with this solution?

Another way to do this, for any string, with two actions:

Regular expression action.
- Pattern = the string you're counting in the pattern (escaping any special characters with a backslash).
- Operation = Extract.
- Input Text = text variable you're searching.
- Store result in collection variable.

Collection operation action.
- Target collection = collection variable from first action.
- Count.
- Store result in: number variable.
