excel运用VBA删除工作表中的重复行

如果要在Excel中用VBA的方法以根据某列内容删除重复的行，即当某列有重复数据时仅保留一行，可以用下面的VBA代码。假如以A列为参考，工作表的第一行为标题行，数据从第二行开始。

方法一：用工作表函数CountIf判断该行是否重复

Sub 删除重复行1()
Dim i As Long
Application.ScreenUpdating = False
For i = Range("A65536").End(xlUp).Row To 3 Step -1
If WorksheetFunction.CountIf(Range("A2:A" & i), Cells(i, 1)) > 1 Then
Cells(i, 1).EntireRow.delete
End If
Next
Application.ScreenUpdating = True
End Sub

方法二：先高级筛选，再删除隐藏行

Sub 删除重复行2()
Dim rCell As Range, rRng As Range, dRng As Range
On Error Resume Next
Application.ScreenUpdating = False
Set rRng = Range("A1:A" & Range("A65536").End(xlUp).Row)
rRng.AdvancedFilter Action:=xlFilterInPlace, unique:=True
For Each rCell In rRng
If rCell.EntireRow.Hidden = True Then
If dRng Is Nothing Then
Set dRng = rCell.EntireRow
Else
Set dRng = Application.Union(dRng, rCell.EntireRow)
End If
End If
Next
If Not dRng Is Nothing Then dRng.delete
ActiveSheet.ShowAllData
Application.ScreenUpdating = True
End Sub
