How to Remove Duplicate Rows in Excel: 2 Proven Ways

This tutorial will teach you how to remove duplicate rows in Excel. Removing duplicate entries in a dataset is a common task among Excel users. Duplicate rows in Excel occur when you are combining different tables together to make one big dataset. Secondly, they can also occur when people are using a shared Excel file which they work on at the same time. Duplicate rows can cause many issues such as giving wrong results if you are using formulas to make calculations. Removing duplicate rows in Excel can be a time consuming and mundane task.

In this post, I will show you two methods on how to delete duplicate rows in Excel which will save you tons of time. The two methods are by using:

  1. The Remove Duplicates button in the Excel ribbon
  2. The Advanced filter button in the Excel ribbon

I will show you how to remove duplicates using both methods with the above dataset. The data shows a list of car sales, which country the car was sold in, and in which quarter. Rows 3 and 10 are highlighted in yellow as they are duplicate entries. Similarly, rows 6 and 13 are also duplicate entries and have been highlighted in orange.

The Remove Duplicates Button to Remove Duplicate Rows in Excel

In order to delete duplicate rows in Excel using the Remove Duplicates button in the ribbon, then please follow these steps.

This means that the first row will not be considered for removing duplicates. You can also check which column headers you want to compare for duplicates under Columns. In my example, I want to check all the column headers, so I have checked all the column header checkboxes. Finally, click on the OK button.

The Advanced Filter to Remove Duplicate Rows in Excel

You can also remove duplicate rows in Excel using the Advanced button in the ribbon. This method filters duplicate values and copies the unique values to a different location. Here are the steps to do this.

This is the most important step. Finally, click on the OK button.
