Highlight duplicate rows across columns by Conditional Formatting

You can highlight duplicate rows across columns by applying a formula in Conditional Formatting function.

1. Select the data range, click Home > Conditional Formatting > New Rule. And in the popping New Formatting Rule dialog, select Use a formula to determine which cells to format, and paste this formula =COUNTIFS($A$2:$A$10,$A2,$B$2:$B$10,$B2,$C$2:$C$10,$C2)>1 into the Format values where this formula is true box. See screenshot:

2. Click Format in the New Formatting Rule dialog to open the Format Cells dialog. In the dialog, click Fill tab, and select one background color that you want to highlight the duplicate rows with. See screenshot:

3. Click OK > OK to close dialogs, and now the duplicate rows across multiple columns have been highlighted with the specified filled color. See screenshot:

Note: in the formula, A2:A10, B2:B10 and C2:C10 are the column ranges you work, you can change them as you need.


If there are dozens of columns you want to work with, the Conditional Formatting would not be a good choice to solve this job. However, you can apply Kutools for Excel’s Select Duplicate & Unique Cells utility to quickly highlight the rows across dozens of columns.

Hello Shosh, you can use this formula =COUNTIF($A$2:$A2, A2)>1 in the Conditional formatting rule, it will highlighted all duplicates except the first one. Hope it can help you.

I think she meant she still needs both columns as part of the equation but have it highlight the lower duplicate instead of the higher duplicate.
