In this comprehensive guide, we’ll show you how to find and remove duplicates in Google Sheets, making your data management tasks easier and more efficient.
Google Sheets is a powerful tool for data analysis and management, and its ability to handle large datasets makes it a favorite among data enthusiasts. However, with great power comes great responsibility, and one of the most common problems that users face is dealing with duplicate data. Duplicates can occur due to various reasons, such as manual errors, data imports, or even software glitches.
Dealing with duplicates can be a tedious and time-consuming task, but with the right techniques and tools, you can quickly identify and remove them. In this article, we’ll explore the different methods for finding duplicates in Google Sheets, including using formulas, filters, and add-ons. We’ll also provide you with step-by-step instructions and examples to help you get started.
Method 1: Using Formulas to Find Duplicates
One of the most common methods for finding duplicates in Google Sheets is by using formulas. You can use the COUNTIF function or the INDEX-MATCH function to identify duplicate values in a range of cells. Here’s how to do it:
Using COUNTIF Function
To use the COUNTIF function, follow these steps:
- Open your Google Sheet and select the range of cells where you want to find duplicates.
- Go to the formula bar and type `=COUNTIF(A:A,A2)>1` (assuming the range is in column A).
- Press Enter to apply the formula.
- The formula will return a count of duplicate values in the range.
Alternatively, you can use the COUNTIFS function to count duplicates based on multiple criteria. For example:
- Open your Google Sheet and select the range of cells where you want to find duplicates.
- Go to the formula bar and type `=COUNTIFS(A:A,A2,B:B,B2)>1` (assuming the range is in columns A and B).
- Press Enter to apply the formula.
- The formula will return a count of duplicate values in the range based on the specified criteria.
Using INDEX-MATCH Function
To use the INDEX-MATCH function, follow these steps:
- Open your Google Sheet and select the range of cells where you want to find duplicates.
- Go to the formula bar and type `=INDEX(A:A,MATCH(A2,A:A,0))` (assuming the range is in column A).
- Press Enter to apply the formula.
- The formula will return the value of the duplicate cell.
Method 2: Using Filters to Find Duplicates
Another method for finding duplicates in Google Sheets is by using filters. You can use the AutoFilter feature to quickly identify duplicate values in a range of cells. Here’s how to do it: (See Also: How to Change Microsoft Excel to Google Sheets? Easily Switch)

- In the Filter view, select the column where you want to find duplicates.
- Click on the “Filter” button and select “Custom filter”.
- In the Custom filter dialog box, select “Duplicate values” and click “OK”.
Method 3: Using Add-ons to Find Duplicates
Google Sheets has a wide range of add-ons that can help you find duplicates in your data. Some popular add-ons include:
Remove Duplicates
This add-on allows you to quickly remove duplicates from your data. Here’s how to use it:
- Open your Google Sheet and select the range of cells where you want to remove duplicates.
- Go to the “Add-ons” menu and select “Remove Duplicates”.
- In the Remove Duplicates dialog box, select the range of cells where you want to remove duplicates.
- Click “Remove duplicates” to remove the duplicates.
Duplicate Finder
This add-on allows you to quickly find duplicates in your data. Here’s how to use it:
- Open your Google Sheet and select the range of cells where you want to find duplicates.
- Go to the “Add-ons” menu and select “Duplicate Finder”.
- In the Duplicate Finder dialog box, select the range of cells where you want to find duplicates.
- Click “Find duplicates” to find the duplicates.
Method 4: Using Conditional Formatting to Highlight Duplicates
You can also use Conditional Formatting to highlight duplicates in your data. Here’s how to do it:
Highlighting Duplicates
To highlight duplicates, follow these steps:
- Open your Google Sheet and select the range of cells where you want to highlight duplicates.
- Go to the “Format” menu and select “Conditional formatting”.
- In the Conditional formatting dialog box, select “Custom formula is” and enter the formula `=COUNTIF(A:A,A2)>1` (assuming the range is in column A).
- Click “Done” to apply the formatting.
Method 5: Using Pivot Tables to Find Duplicates
Pivot tables are a powerful tool for data analysis, and you can use them to find duplicates in your data. Here’s how to do it: (See Also: Can You Zoom Out On Google Sheets? Unveiling The Secret)

The Query function is a powerful tool for data analysis, and you can use it to find duplicates in your data. Here’s how to do it:
Using Query Function
To use the Query function, follow these steps:
- Open your Google Sheet and select the range of cells where you want to find duplicates.
- Go to the formula bar and type `=QUERY(A:A,”SELECT A WHERE A=A”)` (assuming the range is in column A).
- Press Enter to apply the formula.
- The formula will return a list of duplicate values in the range.
