How to delete duplicates in excel column

Answer

To delete duplicates in an Excel column, follow these steps:

1. Select the Column
   Click the header of the column that contains the data you want to check for duplicates. This highlights the entire column.

2. Go to the Data Tab
   Navigate to the Data tab on the ribbon at the top of Excel.

3. Click Remove Duplicates
   In the Data Tools group, click Remove Duplicates.

4. Select Columns to Check
   A dialog box appears. Ensure only the column you want to clean is selected. Multiple columns can be checked if you want to remove rows where all selected column values are duplicates.

5. Confirm Removal
   Click OK. Excel will display a message showing how many duplicate values were removed and how many unique values remain.

6. Finish
   Click OK to close the message. The column now contains only unique values.

Notes:

• The original data is permanently altered. Consider copying the column to a new sheet if you need to preserve the original data.

• Excel treats blank cells as duplicates, so multiple blanks in the column will be reduced to a single blank.

• On Mac, the steps are the same, but the Remove Duplicates option is under the Data tab on the menu bar.

This method is effective for columns with both numbers and text.
