When working with large datasets in Google Sheets, it’s not uncommon to encounter duplicate values. These duplicates can be a result of various factors, such as data import errors, manual data entry mistakes, or even intentional duplication. Whatever the reason, identifying and removing duplicates is crucial to maintaining data accuracy and integrity. In this article, we’ll explore how to see duplicates in Google Sheets, making it easier to manage and clean your data.
Why Identify Duplicates in Google Sheets?
Duplicates can cause a range of issues, from slowing down your spreadsheets to producing inaccurate results. When duplicates are present, it can be challenging to identify the correct data, making it difficult to make informed decisions. Moreover, duplicates can also lead to data redundancy, increasing storage space requirements and making it harder to track changes. By identifying and removing duplicates, you can ensure your data is clean, accurate, and efficient.

Let’s get started and learn how to see duplicates in Google Sheets!
How To See Duplicates In Google Sheets
Identifying duplicates in Google Sheets is an essential task, especially when working with large datasets. In this article, we will explore the various methods to find duplicates in Google Sheets, including using formulas, add-ons, and built-in features.
Method 1: Using the COUNTIF Function
The COUNTIF function is a powerful tool to identify duplicates in Google Sheets. Here’s how to use it: (See Also: What Is Google Sheet Extension)
- Enter the formula `=COUNTIF(A:A, A2)` in a new cell, where A:A is the range of cells you want to check for duplicates and A2 is the cell you want to check.
- Drag the formula down to apply it to the rest of the cells in the range.
- Any cell that returns a count greater than 1 indicates a duplicate.
This method is useful when you want to identify duplicates in a single column or a specific range of cells.
Method 2: Using the INDEX-MATCH Function
The INDEX-MATCH function is another way to identify duplicates in Google Sheets. Here’s how to use it:
- Enter the formula `=INDEX(A:A, MATCH(A2, A:A, 0))` in a new cell, where A:A is the range of cells you want to check for duplicates and A2 is the cell you want to check.
- Drag the formula down to apply it to the rest of the cells in the range.
- Any cell that returns a value indicates a duplicate.
This method is useful when you want to identify duplicates in a single column or a specific range of cells.
Method 3: Using the Conditional Formatting Feature
The Conditional Formatting feature in Google Sheets allows you to highlight duplicates in a range of cells. Here’s how to use it:
- Select the range of cells you want to check for duplicates.
- Go to the “Format” tab and click on “Conditional formatting.”
- Choose the “Custom formula is” option and enter the formula `=COUNTIF(A:A, A2)>1` in the formula bar, where A:A is the range of cells you want to check for duplicates and A2 is the cell you want to check.
- Click on the “Format” button and choose the format you want to apply to the duplicates.
This method is useful when you want to visually identify duplicates in a range of cells.
Method 4: Using the Add-on “Duplicate Detector”
The “Duplicate Detector” add-on is a powerful tool that allows you to identify duplicates in Google Sheets. Here’s how to use it: (See Also: How To Expand All Columns In Google Sheets)
- Go to the Google Sheets add-on store and search for “Duplicate Detector.”
- Install the add-on and follow the instructions to set it up.
- Once installed, select the range of cells you want to check for duplicates and click on the “Detect duplicates” button.
- The add-on will highlight the duplicates in the range.
This method is useful when you want to identify duplicates in a large dataset and need a more advanced solution.
Recap

Key points:
- Use the COUNTIF function to identify duplicates in a single column or range of cells.
- Use the INDEX-MATCH function to identify duplicates in a single column or range of cells.
- Use the Conditional Formatting feature to highlight duplicates in a range of cells.
- Use the “Duplicate Detector” add-on to identify duplicates in a large dataset.

Frequently Asked Questions
What is the easiest way to find duplicates in Google Sheets?
The easiest way to find duplicates in Google Sheets is by using the built-in “Remove duplicates” feature. To do this, select the range of cells you want to check, go to the “Data” menu, and click on “Remove duplicates”. This will show you a list of duplicate values and allow you to remove them.
How do I use the COUNTIF function to find duplicates in Google Sheets?
The COUNTIF function is a powerful tool for finding duplicates in Google Sheets. To use it, enter the formula `=COUNTIF(A:A, A2)>1` in a new column, where A:A is the range of cells you want to check and A2 is the cell you want to check for duplicates. This will return a value of 1 if the cell is a duplicate, and 0 if it’s not.
Can I use a pivot table to find duplicates in Google Sheets?
Yes, you can use a pivot table to find duplicates in Google Sheets. To do this, create a pivot table by selecting the range of cells you want to check, going to the “Insert” menu, and clicking on “Pivot table”. Then, drag the field you want to check for duplicates to the “Values” area, and set the “Group by” option to “Distinct”. This will show you a list of unique values, and any duplicates will be grouped together.
How do I use the FILTER function to find duplicates in Google Sheets?
The FILTER function is another powerful tool for finding duplicates in Google Sheets. To use it, enter the formula `=FILTER(A:A, COUNTIF(A:A, A2)>1)` in a new column, where A:A is the range of cells you want to check and A2 is the cell you want to check for duplicates. This will return a list of duplicate values.
Can I use a script to find duplicates in Google Sheets?
Yes, you can use a script to find duplicates in Google Sheets. To do this, go to the “Tools” menu, click on “Script editor”, and enter the following code: `function findDuplicates() { var sheet = SpreadsheetApp.getActiveSheet(); var data = sheet.getRange(“A:A”).getValues(); var duplicates = []; for (var i = 0; i < data.length; i++) { for (var j = 0; j < data[i].length; j++) { if (data.indexOf(data[i][j]) > -1 && data[i][j] != data[i][j+1]) { duplicates.push(data[i][j]); } } } Logger.log(duplicates); }`. Then, save the script and run it by clicking on the “Run” button. This will log the duplicate values to the console.
