What would you do if you had a String Collection of values and needed to display them on a screen in a human-readable format? Pass this Flow Utility a String Collection and it'll return a String Variable for you to use. Just pass it the String Collection and Finishing Word you want to use and it'll return a String Variable for you to use. Example with "and" as my Finishing Word: Value 1, Value 2 and Value 3 Check out FlowUtilities on Github
