Click Conditional Formatting > Highlight Cells Rules > Duplicate Values. Now the only thing needed is to apply conditional formatting to column E. In the example below, we used the TEXTJOIN function. So we’ll create a kind of “working column” where you can use any concatenation method to join all the values in a row into a single cell. But our real concern is to identify rows that are true duplicates - identical in every way. In the following dataset, each column has a duplicate value somewhere (there are two Roberts, two Longs, four Jersey Cities, and two FLs). Note: visit our page about removing duplicates to learn more about this great Excel tool.If you only want to identify duplicate values in Excel but not remove them, conditional formatting may be just the feature you’re looking for.ĭepending on the type of duplicates you’d like to isolate, you may consider creating an extra column to join the entire row or range of cells into a single string. In the example below, Excel removes all identical rows (blue) except for the first identical row found (yellow). On the Data tab, in the Data Tools group, click Remove Duplicates. Finally, you can use the Remove Duplicates tool in Excel to quickly remove duplicate rows. As a result, cell A1, B1 and C1 contain the same formula, cell A2, B2 and C2 contain the formula =COUNTIFS(Animals,$A2,Continents,$B2,Countries,$C2)>1, etc.ħ. We fixed the reference to each column by placing a $ symbol in front of the column letter ($A1, $B1 and $C1). Excel automatically copies the formula to the other cells. Always write the formula for the upper-left cell in the selected range (A1:C10). Excel highlights the duplicate rows.Įxplanation: if COUNTIFS(Animals,$A1,Continents,$B1,Countries,$C1) > 1, in other words, if there are multiple (Leopard, Africa, Zambia) rows, Excel formats cell A1. =COUNTIFS(Animals,$A1,Continents,$B1,Countries,$C1) counts the number of rows based on multiple criteria (Leopard, Africa, Zambia). Note: the named range Animals refers to the range A1:A10, the named range Continents refers to the range B1:B10 and the named range Countries refers to the range C1:C10. Enter the formula =COUNTIFS(Animals,$A1,Continents,$B1,Countries,$C1)>1Ħ. Select 'Use a formula to determine which cells to format'.ĥ. On the Home tab, in the Styles group, click Conditional Formatting.Ĥ. To find and highlight duplicate rows in Excel, use COUNTIFS (with the letter S at the end) instead of COUNTIF.Ģ. For example, use this formula =COUNTIF($A$1:$C$10,A1)>3 to highlight names that occur more than 3 times. Notice how we created an absolute reference ($A$1:$C$10) to fix this reference. ![]() Excel highlights the triplicate names.Įxplanation: = COUNTIF($A$1:$C$10,A1) counts the number of names in the range A1:C10 that are equal to the name in cell A1. Select 'Use a formula to determine which cells to format'.Ħ. On the Home tab, in the Styles group, click Conditional Formatting.ĥ. First, clear the previous conditional formatting rule.ģ. Execute the following steps to highlight triplicates only.ġ. ![]() ![]() By default, Excel highlights duplicates (Juliet, Delta), triplicates (Sierra), etc.
