Here are some of the most common questions people ask about deleting duplicate rows in Excel, along with helpful answers:
Yes, you can delete duplicate rows in multiple worksheets at once. The easiest way to do this is to select all the worksheets that contain the data you want to check for duplicates. Then, apply the method for removing duplicate rows in one worksheet, and Excel will perform the same procedure in all selected sheets.
Yes, you can undo the deletion of duplicate rows using the undo function in Excel. Click “Ctrl + Z” or click the undo button on the top left of the screen. Alternatively, if you have saved your Excel file without duplicates, you can revert to a previously saved version of the file.
If you are using Excel’s Remove Duplicates tool, and it deletes rows that you didn’t want to delete, don’t worry. You can either undo the deletion or use the Conditional Formatting option to identify duplicates (as mentioned above). This method allows you to identify duplicates visually and remove only the rows you want to delete manually.
Yes, you can automate the de-duplication process in Excel by writing a VBA (Visual Basic for Applications) script. There are several pre-written scripts available online that you can use as a starting point, or you can write your own. Automating your workflow can save you valuable time and reduce the risk of human error.
If you want to check for duplicates across multiple columns, you need to ensure that all columns are selected when removing duplicates. For example, if you have a dataset with first name, last name, and email, you need to select all three columns when removing duplicates. Excel will then only remove rows where all three values match.
