Within previous iterations of the workflow product, there have been functions available to uppercase or lowercase text. I do not find such functions or actions within the NAC workflow product.
Until I can identify how to access such, I built component workflows utilizing regular expressions to accomplish such functions/actions.

Check out the “Toolkit for NWC” in the Nintex Gallery. This xtension for NWC includes functionality for Convert String to Lowercase, Convert String to Proper, and Convert String to Uppercase.
