Highlighting the cells based solely on the name would result in a false highlight in this case. Two of them are duplicates (rows 7 and 27), but there is another entry (row 12) that is unique. In the case of "Michelle Collins" the file contains 3 entries. In column B the highlighting is made using the SUMPRODUCT formula, while cells from column E are highlighted using the built-in Excel conditional formatting. They will have different IDs but the same name. This can be the case when two people with the same name register on a website or if two employees have the same name. In this example, I mentioned that there are some entries that have the same name, but the ID is different. When you apply the new rule, it will highlight all the cells that match the result of our formula. The result of our two Conditional Formatting rules
Note: Keep in mind that all the arrays in the SUMPRODUCT formula must be the same size. Otherwise, SUMPRODUCT will generate a #VALUE! error.

If the value is greater than 1, this means that the combination of ID + Full name is not unique in our table. ĭ) The formula will check if the result returned by SUMPRODUCT is greater than 1 (remember our ">1" condition). The conditional formatting formula will then move to the next set of cells, B4 and E4, and perform the same checks, then continue all the way down to row 202.Ī simple way of looking at this formula would be:Ī) SUMPRODUCT will check if ID from cell B3 is found in the array $B$3:$B$202 and generates an array with only 1s and 0s. Part three checks if the sum resulted from SUMPRODUCT is greater than 1. If they are both true, then it will return a value of 1. Part one and two checks to see if cells from arrays ($B$3:$B$202) and ($E$3:$E$202) match the values from cells B3 and E3 respectively.
#EXCEL FIND DUPLICATE VALUES IN A ROW HOW TO#
The easiest way to understand how to find duplicates in Excel with this conditional formatting formula is to split it into three parts. The COUNTIF function will count the duplicate numbers and then from that, we’ll be able to detect the duplicate rows. Here we’ll use only the COUNTIF function to find duplicate rows in Excel.
Understanding the Conditional Formatting formula Method 3: Insert COUNTIF Function to Find Matched Rows in Excel. Using "*" sign in the formula makes the two conditions cumulative. To display only those values, you can use conditional formatting to highlight the cells with duplicate. Then, it sums all the values and returns the total. Select the values in the column Name and go to the menu Conditional Formatting > Highlight Cells Rules > Duplicate Values menu Conditional Formatting. The numbers 5, 2, and 11 are listed twice in Column B. Type the below formulain cell D2, then copy the formula down until the last row of data see screenshot: CONCATENATE (A2,B2,C2) 2. SUMPRODUCT assigns a value of 1 when the criteria are met, or a value of 0 when the criteria are not met. The first step you should to use the CONCATENATE function to combine all the data into one cell for each row.
