Conditional formatting is typically used to visually highlight or format cells based on certain conditions. It does not have the capability to directly remove duplicates from a column.
To remove duplicates automatically, you can use the built-in feature in Excel called "Remove Duplicates." Here's how you can do it:
1. Select the column containing the names (Column A).
2. Go to the "Data" tab in the Excel ribbon.
3. Click on the "Remove Duplicates" button in the "Data Tools" group.
4. In the "Remove Duplicates" dialog box, make sure that only "Column A" is selected and click the "OK" button.
This will remove any duplicate names from the selected column, leaving only unique values.
If you want to highlight the duplicate names using conditional formatting, you can follow these steps:
1. Select the range of cells in Column A that you want to apply the conditional formatting to.
2. Go to the "Home" tab in the Excel ribbon.
3. Click on the "Conditional Formatting" button in the "Styles" group.
4. Select "New Rule" from the dropdown menu.
5. In the "New Formatting Rule" dialog box, select "Use a formula to determine which cells to format."
6. Enter the formula "=COUNTIF($A$1:$A$100,A1)>1" in the "Format values where this formula is true" field. Adjust the range "$A$1:$A$100" as per your data.
7. Click on the "Format" button to specify the formatting for the duplicate values.
8. Choose the desired format (e.g., font color, background color, etc.) and click "OK."
9. Click "OK" again to apply the conditional formatting rule.
Now, any duplicate names in Column A will be highlighted with the formatting you specified.
Remember, conditional formatting does not actually remove the duplicates; it only visually highlights them. To remove the duplicates, you still need to use the "Remove Duplicates" feature as explained earlier.
