Anyone knows how to replace the empty list by “0” and remain the structure as it is (lists and sublists)? List.ReplaceEmptyList creates separate subs. Not wanted.

@r.vermeulen I suggest you to search the forum. This has been solved multiple times

> Hi, As the name suggests “Replace empty list”, you can see it is asking the replacement also to be a list but you are trying to replace a value with list. What you need to do is create a list with your value (No Description). Then connect tat list to Replacement. Regards, Malthesh
