How to use remove duplicates in excel

Answer

To remove duplicates in Excel, follow these steps carefully:

1. Select the Data Range
   Highlight the range of cells where you want to remove duplicates. Ensure that you include all columns relevant to identifying duplicates.

2. Access the Remove Duplicates Feature

   • On Windows: Go to the Data tab on the ribbon and click Remove Duplicates in the Data Tools group.

   • On Mac: Go to the Data menu, then select Remove Duplicates.

3. Choose Columns to Check for Duplicates
   In the dialog box that appears:

   • Check the columns that you want Excel to consider when identifying duplicates.

   • Leaving all columns checked will remove rows where all selected column values are identical.

4. Confirm the Action
   Click OK. Excel will remove the duplicate rows and display a message indicating how many duplicates were removed and how many unique values remain.

5. Review the Data
   Verify that the intended duplicates are removed. If necessary, undo the action using Ctrl + Z (Windows) or Command + Z (Mac) to restore data and refine the selection.

Tips and Considerations

• Removing duplicates permanently deletes rows from the worksheet. Make a backup before performing this action if the data is critical.

• Excel ignores blank rows when checking for duplicates if the column is selected.

• Conditional formatting can be used prior to removing duplicates to highlight them for review:

  1. Select the range.

  2. Go to Home → Conditional Formatting → Highlight Cells Rules → Duplicate Values.

  3. Choose a formatting style to visualize duplicates.

This method works effectively for large datasets, ensuring data integrity while removing repeated entries.
