Try the StringSplit java action in CommunityCommons, pass your random string as inputString parameter and an empty string (‘’, that is, not “empty”) as splitParameter. You should get a list of SplitItems with a character as the value.
Hi Curtis,
Find the length of the string using that while loop with length > 0 and use substring(string, length-1, 1).
Refer the below mentioned question, in that you can find the way to separate the characters.
