There are a few ways to remove duplicate rows in Excel. One way is to use the Remove Duplicates feature. To do this, select the data you want to check for duplicates, click Data on the ribbon, and then click Remove Duplicates. In the Remove Duplicates dialog box, select the column or columns that contain the duplicates, and then click OK. Excel will remove the duplicate rows and leave the unique rows.
Another way to remove duplicate rows is to use a macro. The following macro will delete all rows that have duplicates in column A. To use this macro, select the data you want to check for duplicates, press Alt+F8, and then run the macro:
Sub DeleteDuplicates() Dim rng As Range Dim cell As Range Dim dict As Object Set rng = Selection Set dict = CreateObject("Scripting.Dictionary") For Each cell In rng If dict.Exists(cell.Value) Then cell.EntireRow.Delete Else dict.Add cell.Value, Nothing End If Next cell Set dict = Nothing End Sub
