Remove Duplicate Rows in Google Sheets: Streamline Data

Here are some ways to find and remove duplicate rows in Google Sheets:

  1. Using Google Script: This method involves using a script that compares each row of data to every other row and highlights the duplicate rows and columns in yellow. To use this method, you need to run the script by clicking on the “Run” button in the script editor. If prompted to authorize the script, click “Continue”. The script will remove any duplicate rows.
  2. Using the built-in “Remove duplicates” feature: This method involves selecting the data range that you want to check for duplicates, then going to the “Data” → “Data cleanup” → “Remove duplicates” option. From the pop-up menu that appears, select which columns you’d like to include in your search for duplicate data. If your spreadsheet includes a header row, be sure to select “Data has header row” so that Google Sheets ignores this row when removing duplicates. Google Sheets will let you know how many duplicate values were removed.
  3. Using an add-on: There are several add-ons available in the Google Workspace Marketplace that can help you find and remove duplicates in Google Sheets. One such add-on is the “Find duplicate or unique rows” add-on, which offers 7 different ways to handle duplicates. It can find duplicates as well as uniques, highlight duplicates in Google Sheets, add a status column, copy/move the results to a new sheet/spreadsheet or any specific place within your spreadsheet, clear found values from cells, and delete duplicate rows from your Google Sheet completely. Once you install it, it will appear under the Extensions.
  4. Using conditional formatting: This method involves highlighting duplicate data in Google Sheets using conditional formatting. To do this, you need to select the data range that you want to check for duplicates, then go to “Format” → “Conditional Formatting”. From the drop-down menu that appears, select “Custom formula is” and enter the formula “=countif(A:A,A1)>1” (without quotes) in the “Value or formula” field. This formula will highlight all duplicate values in column A. You can adjust the formula to suit your needs.

These are some of the ways to find and remove duplicate rows in Google Sheets.
