To find duplicates in Excel, you can use the built-in "Conditional Formatting" feature. Here's how:
1. Select the column that you want to check for duplicates.
2. Go to the "Home" tab in the Excel ribbon and click on "Conditional Formatting."
3. Choose "Highlight Cells Rules" and then "Duplicate Values."
4. In the "Duplicate Values" dialog box, make sure that "Duplicate" is selected under "Format cells with."
5. Choose a format for the duplicates, such as highlighting the cells in red.
6. Click "OK" to close the dialog box and apply the formatting.
This will highlight any cells in the selected column that contain duplicate values. You can then review the highlighted cells to determine if there are any duplicates that need to be removed or merged.
Alternatively, you can use the "Remove Duplicates" feature to remove duplicates from a selected range. To do this, select the range, go to the "Data" tab in the Excel ribbon, click "Remove Duplicates," and follow the prompts to choose the columns to check for duplicates and delete them.
