I have two columns in Excel. Both columns have a list of string that are suffixed with a random character. The format of the prefix is two strings appended by an underscore, and the suffix is added also with an underscore.
ABC_DEF_a => (prefix = "ABC_DEF", suffix = "a")
HJDSGDJ_KJ1_a10 => (prefix = "HJDSGDJ_KJ1", suffix = "a10"
How do I compare if the prefix in Column B is in Column A?
Edit: I know I can do this by splitting the string into three sections, and then combining the first two sections into one column, and then checking if the column is in the other with a VLOOKUP. But I was looking for a oneliner function.
