Count Dups in Two Columns
Hello!
I have two sets of data in Columns A and B. I want to find out how many duplicates there are between column A and column B. I just want the know the total number of duplicates without copying down in another column. In the example below, I want to post the formula in cell A9 to get the number of duplicates...in this case, it's 3. Thanks in advance!!! A B 1 4563 1231 2 1231 1551 3 6598 4563 4 2681 2681 5 32648 165165 6 131 156 7 416516 12 8 9 3 10 |

Not sure if this will have flaws, but one way that seems to work:

Hi,
