Not sure how you are determining duplicate.

Repeated in the same column or occurring in both columns??
1. You have to sort data in Col1 then Col2 (Example in Img1)
2. In C1, =IF(AND(A1=A2,B1=B2),"Duplicated","") (Example in img2)
3. Copy formula down.

Looking at it, I think you are after duplicates of the combination of value in column 1 AND value in column 2. If so, no need to sort the data but use this formula in column 3:


where A:A is column 1 and B:B is column 2; copy down column 3 as far as required.
