The following example shows how to take a range of data in column A and delete duplicate entries. This example uses the AdvancedFilter method of the Range.md) object with theUnique parameter equal to True to get the unique list of data. TheAction parameter equals xlFilterInPlace, specifying that the data is filtered in place. If you want to retain your original data, set the Action parameter equal to xlFilterCopy and specify the location where you want the filtered data copied in theCopyToRange parameter. Once the unique values are filtered, this example uses the SpecialCells method of the Range object to find any remaining blank rows and deletes them.

“vb
Sub DeleteDuplicates()
With Application
' Turn off screen updating to increase performance
.ScreenUpdating = False
Dim LastColumn As Integer
LastColumn = Cells.Find(What:="*", After:=Range("A1"), SearchOrder:=xlByColumns, SearchDirection:=xlPrevious).Column + 1
With Range("A1:A" & Cells(Rows.Count, 1).End(xlUp).Row)
' Use AdvanceFilter to filter unique values
.AdvancedFilter Action:=xlFilterInPlace, Unique:=True
.SpecialCells(xlCellTypeVisible).Offset(0, LastColumn - 1).Value = 1
On Error Resume Next
ActiveSheet.ShowAllData
'Delete the blank rows
Columns(LastColumn).SpecialCells(xlCellTypeBlanks).EntireRow.Delete
Err.Clear
End With
Columns(LastColumn).Clear
.ScreenUpdating = True
End With
End Sub
