How to find and delete duplicates in Excel?

To find and delete duplicates in Excel, you can use the built-in "Remove Duplicates" feature. Here's a step-by-step guide on how to do it:

1. Open your Excel spreadsheet that contains the data with potential duplicates.
2. Select the range of cells or columns where you want to check for duplicates. Make sure to include the column headers if you have them.
3. Go to the "Data" tab in the Excel ribbon at the top.
4. In the "Data Tools" group, you'll find the "Remove Duplicates" button. Click on it.
5. A dialog box will appear with a list of columns in your selected range. By default, all columns are selected. You can choose to include or exclude specific columns based on your needs.
6. Once you have selected the appropriate columns, click the "OK" button.
7. Excel will scan the selected range and identify any duplicate values.
8. After the scanning is complete, a dialog box will appear, informing you of the number of duplicate values found and removed. Click the "OK" button.
9. Excel will remove the duplicate values from your selected range, keeping only the unique values. The remaining data will be rearranged accordingly.

Note: The "Remove Duplicates" feature permanently deletes the duplicate values. Make sure to save a backup of your data before proceeding, in case you need to revert any changes.

By following these steps, you should be able to find and delete duplicates in your Excel spreadsheet.
