Excel - Search for duplicate in adjacent columns


I have 4300 old applicant numbers which I need to check against 3300 new applicant numbers in two columns next to each other. Is there any formula under Excel to resolve this matter?


If two numbers are in adjacent columns you can use the match function.

  • E.g, in cell c2 you can write this:
  • =IF(ISERROR(MATCH(B2,A:A,0)), "", MATCH(B2, A:A,0))
