This will show you all the cells that have at least one duplicate email address. Then just combine the results using a formula like this:ĬOUNTIF(C$2D13, C14) + COUNTIF(C$2D13, D14) If you do the same for the second column(D), you will get the duplicate cells in the D column as well. Then you can copy-paste the cell to the rest of the columns to search for each cell value in the range. Searches for the value of C14 in the cell range C2D13 In this case, we just compare the value of the cell with all cell values in a range. We can use the COUNTIF() function to count the cell that matches certain criteria. You want to find the duplicate email address in either of the columns. Suppose you have a google sheet with a “primary email” and “secondary email” fields. In this article, we will see how to find duplicates when there are more than one columns to search for duplicates. in rangesīy highlighting duplicates in your ranges you’ll be better able to warn users if they have accidentally typed a value that needs to be unique.In another article here ( In Google Sheets, how to highlight duplicates using a simple formula ), we had discussed how to highlight duplicates using the MATCH() function. =COUNTIF(INDIRECT("A1:Z1"), INDIRECT("RC", FALSE)) + COUNTIF(INDIRECT("C3:F5"), INDIRECT("RC", FALSE)) > 1Īnd this formula being pasted in each custom formula’s conditional formatting range (i.e. Representing the repeated formula again for each contiguous range. Is the range you want to check for duplicates and the Here are the steps to follow: In the second row of column C (in cell C2), insert the formula: A2B2. The above formula compares data in row 2 of both columns to see if they match. =COUNTIF(INDIRECT("range"), INDIRECT("RC",FALSE)) +. The formula you would use for a comparison like this is: A2B2. If you want to highlight duplicates in non-contiguous ranges modify the formula slightly by making the formula: Matches the highlighted range applied for the conditional formatting. To highlight cells that are duplicated in a range, use the conditional formatting custom formula functionality with the formula Multiple times per unique range and set conditional formatting on each range.Īs you can see from the result, the highlighted cells which can be found in both the top row and the rectangular ranges are highlighted. To highlight duplicates in non-adjacent ranges use the Here’s the result of applying the above formula to the two ranges which are not connected or joined (I’ve highlighted the entire sheet to show that conditional formatting custom formulas will be needed in both the ranges): =COUNTIF(INDIRECT("topRow"),INDIRECT("RC",FALSE)) +ĬOUNTIF(INDIRECT("rect"),INDIRECT("RC",FALSE)) > 1 You could make it easier by naming the ranges, like so: =COUNTIF(INDIRECT("A1:Z1"),INDIRECT("RC",FALSE)) +ĬOUNTIF(INDIRECT("C3:F5"),INDIRECT("RC",FALSE)) > 1Įach range you would want to check again would need to be defined in its ownįunction, with every range wrapped in the first parameter with The same formula is used, however, for each range, you would need to perform one slight change: you need to useĪnd see if both ranges contained duplicates my new formula for checking these ranges would now look like this: How can you highlight duplicates in ranges that are not joining? Highlight Duplicates In Multiple Non-Contiguous Ranges Using the same formula and concept can apply to rows tooĬan the same formula work with multiple non-joining ranges?
