Usando o VBA:
Public Function allDuplicates()
Dim a As Application
Set a = Application
Dim arrayRows() As Boolean
maxCol = 2
firstRow = 2
Dim wks As Worksheet
Set wks = ActiveSheet
wks.Application.ScreenUpdating = False
totalRows = wks.Cells(Rows.Count, "A").End(xlUp).Row
ReDim arrayRows(totalRows)
For i = firstRow To totalRows
theRow = Join(a.Transpose(a.Transpose(wks.Range(Cells(i, 1), Cells(i, maxCol)))), Chr(0))
For j = i + 1 To totalRows
theOtherRow = Join(a.Transpose(a.Transpose(wks.Range(Cells(j, 1), Cells(j, maxCol)))), Chr(0))
If theRow = theOtherRow Then
arrayRows(i) = True
arrayRows(j) = True
End If
Next j
Next i
For i = firstRow To totalRows
If arrayRows(i) = True Then
wks.Rows(i).Clear
End If
Next i
Range("A1:B" & totalRows).Sort key1:=Range("A2:A" & totalRows), order1:=xlAscending, Header:=xlYes
wks.Application.ScreenUpdating = True
Message = MsgBox("Finished", vbInformation)
