i am trying to match same IDs in two different list.
Convert to integer or string first.
yes i convert the ids in to String
Can i change Id to element again
What is your end goal? What are you trying to accomplish? It might be easier if you could show what you have so far.
IDs to elements will allow for that. Believe that can be found in archilab and bakery but I may be wrong. Hard to know because as @Nick_Boyts noted we can’t see what you’re after here.
