There are a few ways to remove duplicates in Google Sheets. You can use the built-in function called "Remove Duplicates," which will delete all duplicate rows from your sheet. You can also use the "Filter" function to delete duplicate rows. To do this, go to the "Filter" tab and select "Duplicates." This will show you a list of all the duplicate rows in your sheet. You can then select the rows you want to delete and click "Delete."
