Finding Duplicates in Google Sheets: A Comprehensive Guide
Introduction
Google Sheets is a powerful tool for data analysis and manipulation. One of its most useful features is the ability to find duplicates in a table. Duplicates can be caused by errors, inconsistencies, or simply the way we organize our data. In this article, we will explore how to find duplicates in Google Sheets, and provide you with a step-by-step guide on how to do it.
Step 1: Select the Range
Before we can start finding duplicates, we need to select the range of cells that we want to examine. To do this, select the entire range by pressing Ctrl+A or by selecting the entire row or column by clicking on it.
Step 2: Use the "DDuplicate" Formula
The most straightforward way to find duplicates in Google Sheets is to use the Dduplicate formula. Here’s how to do it:
- Select the entire range of cells that you want to examine.
- In the top right corner of the Google Sheets editor, you will see a box that says "Entire Sheet". Select this box.
- Next to the box, you will see a dropdown menu. Click on the "DDuplicate" formula. This will create a new column with the duplicates.
- The formula will look like this: =D:D2
- This formula will return all duplicates in the selected range.
Step 3: Filter the Duplicates
To get rid of the duplicates, you need to filter the column. Here’s how:
- Select the entire range of cells that you want to examine.
- Click on the DDuplicate formula, and press Ctrl+Enter to enter the formula.
- The formula will look like this: =D:D2
- To filter the duplicates, click on the 2 icon in the formula bar.
- This will open a menu with two options: "Delete" and "Show duplicates". Click on the "Delete" option to remove the duplicates.
Step 4: Delete the Duplicates
To delete the duplicates, you need to select the range that you want to remove. Here’s how:
- Select the entire range of cells that you want to examine.
- Click on the 2 icon in the formula bar.
- The "Delete" option will prompt you to confirm whether you want to delete the duplicates. Click on the "Yes" button to remove the duplicates.
Step 5: Use Conditional Formatting
If you want to highlight the duplicates, you can use conditional formatting. Here’s how:
- Select the entire range of cells that you want to examine.
- Go to the "Format" tab in the top menu.
- Click on the "Conditional formatting" button.
- Select "Custom formula is" and enter the formula:
=D:D - The formula will highlight all duplicates.
Step 6: Create a Table to Display Duplicates
To make it easier to understand the duplicates, you can create a table to display them. Here’s how:
- Select the entire range of cells that you want to examine.
- Go to the "Data" tab in the top menu.
- Click on the "New table" button.
- The table will automatically be created with columns for the duplicates and the row number.
Tips and Tricks
- To find duplicates in a specific column, select that column and use the DDuplicate formula.
- To filter the duplicates, click on the 2 icon in the formula bar.
- To delete the duplicates, select the range and click on the 2 icon in the formula bar.
- To highlight the duplicates, select the entire range and go to the "Format" tab in the top menu.
- To create a table to display duplicates, select the entire range and go to the "Data" tab in the top menu.
Using the "Look Up" Function
The "Look Up" function is another powerful tool in Google Sheets that can help you find duplicates. Here’s how to use it:
- Select the entire range of cells that you want to examine.
- Go to the "Functions" tab in the top menu.
- Click on the "Look Up" button.

=LLookUp(D:D2,"=D[C*C]" - The formula will return the range of cells that have the same value as the last row of the table.
Conclusion
Finding duplicates in Google Sheets is a straightforward process that can be done using the "DDuplicate" formula, conditional formatting, and the "Look Up" function. By following these steps and tips, you can easily identify and eliminate duplicates in your Google Sheets data.
