Finding duplicates in Excel can be really handy to clean up your data! One way is to use Conditional Formatting. Just select your data range, go to the "Home" tab, click "Conditional Formatting," choose "Highlight Cells Rules," and then "Duplicate Values." Another method is using the "Remove Duplicates" feature under the "Data" tab. Have you encountered duplicates in a specific kind of data? I'd love to hear more about how you work with Excel and any challenges you face!
