It will copy the content to where the formula applied. It’s very easy to use the unique function. Just type “unique(” and select the entire data and close the bracket. Press enter key to see the result! Delete the first data as you have already got the data without duplicates. Thus you can use the unique() function to remove duplicate data.

Note: Dynamic Formula to Find and Mark Duplicates

Things to remember!

The Google Sheets UNIQUE formula will check the data range for duplicates. For example in the above, the duplicate contents are in first and last row. If the “Year Published” is different in both rows, the above function will considered both as separate entry, not unique.

If you want to colour the duplicates, or remove it permanently from the existing data itself, use the add-on “Remove Duplicates” from the add-on menu. Hope you enjoyed this Google Doc Spreadsheet tips.
