I have a context id value that is comma separated. Which function allows me to parse it based on the comma? I do not recall seeing anything that allows parsing based on a specific character?

I am assuming you are asking about the functions available in ED Expression Builder. There is no direct function today that will separate all of the substrings based on the separator as comma in one go. But you can use the split function to achieve the same result - one split at a time, and do that in a loop. I can build a sample workflow and attach here if you like. Please let me know.

Definitely would like to see that. Thanks.
