I want to remove everything before the colon, so that only the names are left. My current formula does that but it puts a #!Value error if there is no colon. It should change nothing and just copy the exact name if no ":" is present.
Column C
key1:john
key1:mike
key1:edmund
hello
key3:edmund
etc
My formula =IFERROR(RIGHT(C1,LEN(C1)-FIND(":",C1)),"")
Column D
john
mike
edmund
#!Value
edmund
etc
