How to remove duplicates from a list in Excel?

To remove duplicates from a list in Excel, you can use the built-in "Remove Duplicates" feature. Here's how:

1. Select the range of cells that you want to remove duplicates from.
2. Go to the "Data" tab in the Excel ribbon.
3. Click on the "Remove Duplicates" button in the "Data Tools" group. This will open the Remove Duplicates dialog box.
4. By default, Excel will select the entire range you initially selected. If you only want to check specific columns for duplicates, uncheck the boxes for the columns you want to exclude.
5. Click the "OK" button.
6. Excel will remove any duplicate values from the selected list and display a message box indicating how many duplicates were removed.

Note: This process permanently removes duplicate values from the list, so make sure to keep a backup of your original data if necessary.
