How To Find Duplicates In Two Google Sheets
Identifying duplicates in two Google Sheets can be a tedious task, but with the right tools and techniques, it can be done efficiently. In this article, we will guide you on how to find duplicates in two Google Sheets using Google Sheets’ built-in functions and add-ons.
Method 1: Using Google Sheets’ Built-in Functions
To find duplicates in two Google Sheets using Google Sheets’ built-in functions, follow these steps:
-
Open both Google Sheets and select the entire data range in each sheet.
-
Go to the “Edit” menu and select “Copy” to copy the data range in the first sheet.
-
Open the second sheet and go to the cell where you want to find the duplicates.
-
Paste the data range from the first sheet into the second sheet using the “Paste” option.
-
Select the entire data range in the second sheet and go to the “Data” menu.
-
Select “Filter views” and then “Create new filter view” to create a filter view of the data. (See Also: How To Make An Attendance Sheet In Google Forms)

This method is simple and easy to use, but it may not be efficient for large datasets.
Method 2: Using Google Sheets’ Add-ons
Another way to find duplicates in two Google Sheets is by using Google Sheets’ add-ons. One popular add-on for this purpose is the “Duplicate Remover” add-on.
To use the “Duplicate Remover” add-on, follow these steps:
-
Open the Google Sheets add-on store and search for “Duplicate Remover”.
-
Install the add-on and grant the necessary permissions.
-
Open both Google Sheets and select the entire data range in each sheet.
-
Go to the “Tools” menu and select “Duplicate Remover” to open the add-on.
-
Select the columns that you want to use to find duplicates.
-
Click the “Find duplicates” button to find and highlight the duplicates in the data. (See Also: How To Group And Collapse Rows In Google Sheets)
This method is more efficient than the first method, especially for large datasets.
Method 3: Using Google Apps Script
You can also use Google Apps Script to find duplicates in two Google Sheets. This method requires some programming knowledge, but it is a powerful way to automate the process.
To use Google Apps Script to find duplicates, follow these steps:
-
Open the Google Sheets script editor by going to the “Tools” menu and selecting “Script editor”.
-
Write a script that reads the data from both Google Sheets and finds the duplicates.
-
Use the `getRange()` and `getValues()` methods to read the data from both sheets.
-
Use the `filter()` method to filter the data and find the duplicates.
-
Use the `getRange()` and `setValues()` methods to write the duplicates to a new sheet.
This method is more advanced and requires some programming knowledge, but it is a powerful way to automate the process.
Recap
In this article, we have discussed three methods for finding duplicates in two Google Sheets. The first method uses Google Sheets’ built-in functions, the second method uses a Google Sheets add-on, and the third method uses Google Apps Script. Each method has its own advantages and disadvantages, and the choice of method will depend on the size and complexity of the data.
