How to delete duplicate rows in excel?

To delete duplicate rows in Excel, you can use the built-in feature in Excel called "Remove Duplicates" or perform the procedure using the "Remove Duplicate Rows" function. Here's how to do both:

Using Excel's Built-In Feature (Remove Duplicates):

  1. Open the Excel file containing the data you want to clean.
  2. Select the range of data that you want to check for and remove duplicate rows.
  3. In the "Data" tab, you will find the "Remove Duplicates" option. Click on it.
  4. A "Remove Duplicates" dialog box will appear. Here, you can choose the column or columns that you want to use to identify duplicate rows. Then, click the "OK" button.
  5. Excel will remove the duplicate rows based on the column you selected and display a message indicating the number of rows removed.

Using Formulas (IF + COUNTIF):

  1. Create a new column (e.g., column C) next to the data you want to check for duplicates.
  2. In column C, use the following formula to check if a row is a duplicate: =IF(COUNTIF(A:A, A2)>1, "Duplicate", "Unique") In this formula, A:A represents the column that contains your data (change the column name if necessary), and A2 is the cell being evaluated. This formula will display "Duplicate" if the row is a duplicate, and "Unique" if it's not.
  3. Now, you can sort the data based on column C. All rows with "Duplicate" values in column C will be grouped together.
  4. Then, you can select and delete the duplicate row

Choose the method that suits your needs and the nature of your data. The "Remove Duplicates" method is typically faster and more convenient, while the COUNTIF formula allows you to customize the criteria for checking duplicates.
