Hello everyone,

I am struggling to come up with a formula to find every unique value between two different columns. I would want it to identify a unique number only if it is unique between the two columns i.e if "5417" is in once on column A and once on Column B I am fine with that. That would make it a duplicate.

The ultimate goal is to identify these so I can delete them out and see the same numbers essentially in both columns. I can't do conditional formatting and filter because my data is 60,000+ rows long and it just won't work.

I am perfectly fine with some sort of helper column. Thanks!!!!

To eliminate the unique values in column A this in cell B2 and copy down.
Code:
=IF(COUNTIF(C:C,A2)=1,A2,"")
Then in cell D2 put this and copy down to eliminate unique values in column C.
Code:
=IF(COUNTIF(A:A,C2)=1,C2,"")

Hi,

I would actually like it to be the ones that are unique when both columns are combined together. Thanks!!

Guess I misunderstood this statement. So if you change the 1 to 0 in both formulas, it would then list the items unique to each column.
Code:
=IF(COUNTIF(C:C,A2)=0,A2,"")
