Introduction
If you’re working with data in Excel, chances are you’ve encountered duplicates. These are data entries that appear more than once in your worksheet, making your data look untidy and potentially affecting your analyses. This article is aimed at Excel users of all levels who want to learn how to remove duplicates in their worksheets.
Removing duplicates is an essential skill for data cleaning in Excel. It can save you time and effort in your analysis, as well as help prevent errors and ensure accurate results. In this article, we’ll go through a step-by-step guide on how to remove duplicates, provide beginner-friendly explanations, highlight best practices and introduce some Excel add-ins that can help you streamline your duplicate removal process.
Step-by-Step Guide
Removing duplicates in Excel is a simple process that can be done with a few clicks. Here’s how to do it in three easy steps:
1. Select the data range that you want to remove duplicates from.
2. Click on the ‘Data’ tab in the ribbon at the top of the window.
3. Click on the ‘Remove Duplicates’ button in the ‘Data Tools’ section.
Excel will then prompt you to select the columns you want to check for duplicates. Make sure the box next to each column of interest is checked, then click ‘OK.’ If you want to keep a copy of the duplicates, make sure the ‘Copy to another location’ checkbox is selected, then choose the range where you want the copy to appear.
Beginner’s Guide
Before we dive into the step-by-step guide, let’s clarify what duplicates are. Duplicates occur when there are multiple entries of the same data in your worksheet. For example, if you have a list of names and two people have the same name, you’ll have duplicates.
Removing duplicates in Excel is straightforward. Start by selecting the data range that you want to clean, as described in the step-by-step guide. If you’re not sure which columns to select, consider what makes an entry unique. For example, if you have a list of students, you might choose to remove duplicates based on student ID numbers rather than names, as two students could have the same name but different IDs.
It’s important to note that removing duplicates can affect your data, so it’s always a good idea to make a backup copy of your worksheet before getting started. You might also want to consider whether there are any other data cleaning tasks you need to perform before removing duplicates.

Best Practices
When removing duplicates in Excel, there are a few best practices to keep in mind:
– Always make a backup copy of your worksheet before removing duplicates.
– Carefully select the columns that you want to check for duplicates.
– Check for duplicates based on what makes an entry unique.

– Be mindful that removing duplicates can affect formulas and calculations in your worksheet.
When dealing with larger datasets, it may be helpful to use Excel’s filtering tools to identify duplicates before removing them. You can also use Excel’s ‘Conditional Formatting’ tool to highlight duplicates automatically, making them easier to spot.

Kutools for Excel includes a ‘Remove Duplicates’ feature that highlights unique values and can remove duplicates based on one or more columns.
