If you need to expand your comparison you will need to highlight all the rows, in the column, where you want the common values stored. Paste the above equation into the formula box, may need to use F2 button, and change the values of 17 to however many rows you need. The "" portion of the equation will need retyped as "". Use CTRL + SHFT + ENTER to run comparison. This is due to the equation using an array. Good Luck

Thank you for your comment. I have edited the article.

hi oscar,

i have a small problem which is similar to the one you have illustrated above, with the only difference being that i have some duplicates within List1 and List2 themselves.

eg. GG is repeated twice in List1, HH is repeated thrice in List2.

when i use this formula, i get duplicate GG and HH in Column 3. is there a way to prevent them from appearing? i tried a mishmash of this formula and a couple of others that i learnt on your website (ones listed in Duplicate category), but to no avail.

please help me out; i will appreciate that very much.

much thanks and kind regards.

K. Yantri,

Hi Oscar,

Thanks for your quick reply.

PSB the proper example of my prob:-

Question 1 How can we identify duplicate values from each column?

Question 2 If it is not possible to compare 4 column can we do it for 2?

Data 1 Data 2 Data 3 Data 4

1 5 9 11

2 6 10 12

3 4 4 4

4 7 7 7

5 8 8 8

Multi-nested formulas, as the one above, can be tough to decipher

The free/unlocked function syntax and usage navigation Add-in (link below) can speed-up your modelling work, if you are:

1) looking for multi-lingual documentation or translation for a function

2) searching for a new function to simplify your formulas

3) wondering, if a function is backwards compatible with previous Excel versions

Very helpful, thanks!

BTW one can also use this simple online tool to ensure that the formula is correct:
