How to highlight multiple columns using different colors You’ll need to frame every cell with a “$.” Our function becomes =COUNTIF ($B$1:$C$50, B1)>1.

For example, if we want to look at columns C through F now, we’ll update “Apply to range” to “C1:F999” and then make sure the function reads =COUNTIF(C:C, C1)>1. Make sure the syntax of your formula matches the first value. Rather than clear the conditional formatting, highlight your new columns, and start over, you can simply update the “Apply to range” to read “B1:F999.” Let’s say you were looking at columns B and C, but now you want to include columns B through F. You can adjust the range in Apply to range as needed. That tells Sheets to start with B1 and go from there. Use 'Apply to range.'īy highlighting the columns you want to check, you’ll automatically tell Apply to range what to concentrate on, but you’ll have to adjust your custom formula to start with the value of that first column and first row.įor our purposes, we’re looking at columns B and C, so our function should be =COUNTIF(B:B, B1)>1.

We’ve purposely added an error in the titles column, repeating Batman twice.

Let’s say you want to check movie titles and directors, so columns B and C in this case.

How to count duplicates in multiple columns You can see how it begins to highlight repeat directors. Our formula should become =COUNTIF (C:C, C2)>1. Since we’re looking for duplicate directors, we want to adjust the formula to read the C column. The information outside the parentheses states that you want Sheets to count duplicates, or anything appearing more than once (>1). The information in the parentheses represents the column you want to track and the specific cell you want to start with. The COUNTIF formula tells Sheets where to look for duplicates. Use the COUNTIF formula to find duplicates. In the 'Format cells if' box, click 'Custom formula is.'ĥ.
