If you need to average a list of values in Microsoft Excel that contain duplicates without including the duplicates, don't fret over a complex expression when you can easily remove those duplicates.

You can then delete the unique values from the spreadsheet or simply copy the duplicate values to a new spreadsheet to separate them from the non-duplicate values.

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

In this guide, we will explore three primary techniques for removing duplicates: handling single column duplicates, managing multiple columns, and using formulas to extract unique values.

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

Excel will display a message indicating how many duplicates were removed and how many unique values remain. This method is quick and effective, especially for small to medium-sized datasets.
