How to Delete Duplicates in Microsoft Excel
-
Deleting Entire Rows
To delete entire rows, select the range of cells, go to the ‘Data’ tab, and click on ‘Remove Duplicates’. Confirm the columns you want to check, and Excel will delete the entire row for each duplicate found. This method is quick and efficient, but it does not give you the chance to review the duplicates before deletion. Make sure to create a backup of your data before proceeding.

Deleting Duplicate Values
If you only want to delete the duplicate values but keep the rest of the row intact, you can use a combination of the ‘IF’, ‘COUNTIF’, and ‘IFERROR’ functions. This method is more complex and requires a good understanding of Excel functions. The ‘IF’ function allows you to perform a certain action if a condition is met. The ‘COUNTIF’ function counts the number of times a certain value appears in a range. The ‘IFERROR’ function allows you to handle errors that might occur during the calculation. By combining these functions, you can create a formula that checks each value in a range, counts how many times it appears, and deletes it if it appears more than once.
