Sometimes, there are may be some duplicate records in your data range of a worksheet, and now you want to find or highlight the duplicate rows in the range as following screenshots shown. Of course you can find them one after one by checking for the rows. But this is not a good choice if there are hundreds of rows. Here, I will talk about some useful ways for you to deal with this task.
The following formula can help you to find the duplicate records, please do as this:
1. In the adjacent blank cell, cell D2 in this case, please enter the below formula:
2. And then drag the fill handle down to the cells for applying this formula, now, you can see, if there are identical rows in this used range, it will display Duplicate row, see screenshot:
- 1. In the formula, $A$2:$A$12, $B$2:$B$12, $C$2:$C$12 indicate the range columns that you want to find the duplicate from. You can change them as you want. And A2, B2, C2 indicate the first cells in the each column of the data which needed to be applied this formula, you can change them as well.
- 2. The above formula is based on data in 3 columns, if there are 4 or more columns in your data range which needed to be found the duplicated values from the first row, you just need to add the column references as this formula shown: =IF(COUNTIFS($A$2:$A$12,$A2,$B$2:$B$12,$B2,$C$2:$C$12,$C2,$D$2:$D$12,$D2)>1, "Duplicate row", "").

1. The first step you should to use the CONCATENATE function to combine all the data into one cell for each row. Type the below formulain cell D2, then copy the formula down until the last row of data see screenshot:
2. Then, select the range that you want to find the duplicate rows including the formulas in column D, and then go to Home tab, and click Conditional Formatting > New Rule, see screenshot:
3. In the New Formatting Rule dialog box, please do the following operations:
- Click Use a formula to determine which cells to format from the Select a Rule Type list box;
- And then, enter this formula =COUNTIF($D$2:$D$12,$D2)>1 (Highlight duplicate rows with first occurrences) or =COUNTIF($D$2:$D2,$D2)>1 (Highlight duplicate rows without first occurrences) into the Format values where this formula is true text box;
- At last, click Format button.
4. In the popped out Format Cells dialog box, click Fill tab, and then, choose one color that you need to highlight the duplicates.
