Duplicate Rows in Excel: How to Find and Remove Them

Removing duplicate rows in Excel is pretty straightforward. You just need to identify the rows that are duplicates and then delete them. After reading this article, you’ll know exactly how to accomplish that task like a pro.

Step by Step Tutorial to Remove Duplicate Rows in Excel

Before we dive into the steps, it’s important to understand what we’re aiming to achieve here. We want to get rid of duplicate rows to keep our data clean and accurate. This is essential for any data analysis or reporting task. Let’s get started.

Step 1: Select the Data Range

Select the range of cells that you want to check for duplicates.

Selecting the right data range is crucial. If you select too little, you might miss some duplicates. If you select too much, you might accidentally remove unique rows.

Step 2: Click on ‘Data’ tab

Navigate to the ‘Data’ tab on the Excel ribbon.

This is where all the magic happens. The ‘Data’ tab is like the control center for all things related to data management in Excel.

Step 3: Click on ‘Remove Duplicates’

Click on the ‘Remove Duplicates’ button within the ‘Data Tools’ group.

Make sure to double-check that you have the correct range selected before you hit ‘Remove Duplicates’. You don’t want to remove something important by accident!

Step 4: Choose the Columns to Check

In the dialog box, choose which columns you want to check for duplicate data.

If you’re not sure which columns to check, it’s better to be safe than sorry. Check all columns to make sure you’re not missing any duplicates.

Step 5: Click ‘OK’

After selecting the columns, click ‘OK’ to remove the duplicate rows.

And just like that, you’ve cleaned up your data! It’s always a good feeling to get rid of clutter, isn’t it?

After you complete the action, Excel will remove all the duplicate rows based on the criteria you set. It will also tell you how many duplicate rows were found and removed. Now, you have a clean dataset to work with!
