# How to Remove Duplicates of a Given Row using Formula?

Here is a sample (simplified) scenario that I am trying to resolve.

Given...
 Tom Peter Sam Susan Combo1 1 2 1 3 Combo2 A A B A Combo3 ! @ # \$ Combo4 a b b c

<COLGROUP><COL style="WIDTH: 54pt" span=5 width=72><TBODY>
</TBODY>

Trying to make it into this by removing all the duplicates:
 Combo1 1 2 3 Combo2 A B Combo3 ! @ # \$ Combo4 a b c

<COLGROUP><COL style="WIDTH: 54pt" span=5 width=72><TBODY>
</TBODY>

Is there any method using formula? I am preferring formula (over macro or advanced filter) because it would dynamically update the result if the value in given table changes.

### Excel Facts

What does custom number format of ;;; mean?
Three semi-colons will hide the value in the cell. Although most people use white font instead.

Hi,

You won't be able to have the original table values replaced as desired without VBA, though if you are happy with having a different table which updates to give your desired results then, assuming the original table as you give it is in the range A1:E5 (with headers in row 1 and column A), create another table (with identical dimensions and headers), enter this formula in the topleftmost cell and then copy across and down to fill the table:

=IF(COLUMNS(\$A:A)>SUMPRODUCT(1/COUNTIF(\$B2:\$E2,\$B2:\$E2)),"",OFFSET(B2,,SUMPRODUCT(--(FREQUENCY(MATCH(\$B2:B2,\$B2:B2,0),MATCH(\$B2:B2,\$B2:B2,0))>1)),,))

Regards

Thank you. You are too smart.

How do you find the answer so quickly to random questions?

Probably as I am fortunate enough to be able to see order within that apparent randomness!

Glad I could help and thanks for the feedback.

Excel contains over 450 functions, with more added every year. That’s a huge number, so where should you start? Right here with this bundle.
