Microsoft Excel is perhaps the most powerful spreadsheet application you can buy. But it also has some simple functions, like finding duplicates in data.

Install the Remove Duplicates add-on from the Google Workspace Marketplace. In your sheet, click Extensions, then Remove Duplicates, and choose: Find Duplicates or Uniques.

You can remove duplicates in Excel in a few steps. Duplicates can create problems when you're dealing with data.

If you want duplicate values to stand out in an Excel spreadsheet, you can choose between two conditional formatting rules.
