The image below explains what I’m after. I can get it to work with one value by using ReplaceByCondition and the String.Contains node, but for the life of me I cannot figure out how to make it work for a list. I need to iterate through each item in List A and search each item in List B. Once found, replace with the item found in list B, then move on to the next item in List A & repeat. Any ideas? I’m tired and stuck Thanks!
