This will open a dialog box asking you to confirm the columns from which you want to remove/delete the duplicates. Click OK and the duplicate data will be removed/deleted.

Using a Formula

Another way to remove duplicate data in Excel is by using a formula. To do this, select the column or range of cells containing the duplicate data. Then, enter the following formula into the top cell of the selected range: =IF(COUNTIF(A:A,A1)>1,"",A1). This formula will check each cell in the selected range and return a blank value if the cell is a duplicate. Once the formula has been entered, copy the formula to the remaining cells in the range. The duplicate data will now be removed/deleted.

Using a Macro

Using a macro is also an effective way to remove duplicate data in Excel. To do this, open the Excel file that contains the duplicate data. Then, select the column or range of cells containing the duplicate data. Next, open the Visual Basic Editor (VBE) by pressing Alt + F11. In the VBE, create a new macro and enter the following code: Sub RemoveDuplicates() Range("A:A").RemoveDuplicates Columns:=1, Header:=xlNo End Sub. This code will remove/delete all duplicate values in the selected column or range. Finally, run the macro and the duplicate data will be removed/deleted.
