How to Remove Duplicates with Excel


Learn how to remove duplicates with Excel.

Removing duplicates manually can be time-consuming when working with large data sets.

The Remove Duplicates function in Excel makes removing duplicates easy.


The Remove Duplicates function Remove duplicates button is used to remove duplicate entries.

Duplicate entries are values that two or more are the same.

This can be both numbers and text inputs.

Example

A1(5), A2(5), A3(2)

A1 and A2 are duplicates since they have the same values.


How to remove duplicate values

Step 1) Select a range:

Select the range where you want to remove duplicate values.

A minimum of two cells needs to have values.

Selected range

Excel will automatically include related cells.
