当你想去重复你的列表，这是确保你只有一个项目剩下的每个，你可以这样：

在 Excel 2007 及更高版本中，您可以在“数据”菜单中删除重复项，这将为您完成。

在 Excel 2003 及更早版本中，您可以使用数据 / 过滤器菜单中的高级过滤器：

然后将结果复制粘贴到新工作表中。

您可以看到完整的过程here.

否则它是一个乏味的宏来写 (一个递归循环来检查值是否存在于集合中),它是可以做到的,但是你真的需要它吗?

但是，如果你想实际删除所有相同的条目，那么使用 @ Eoins 的宏将完成这项工作，但有点修改如下：

Option Explicit
Sub DeleteDuplicate()
    Dim x, Y As Long
    Dim LastRow As Long
    Dim myCell As String
    LastRow = Range("A1").SpecialCells(xlLastCell).Row
    For x = LastRow To 1 Step -1
        myCell = Range("A" & x).Text
        If Application.WorksheetFunction.CountIf(Range("A1:A" & x), myCell) > 1 Then
            For Y = x To 1 Step -1
                If Range("A" & Y).Text = myCell Then
                    Range("A" & Y).EntireRow.Delete
                End If
            Next Y
        End If
    Next x
End Sub

由于您的请求是宏，请尝试：

Excel 2007 +

ActiveSheet.Range("A:A").RemoveDuplicates

这是您的 Excel 2003 选项

Option Explicit
Sub DeletDuplicate()
    Dim x As Long
    Dim LastRow As Long
    LastRow = Range("A65536").End(xlUp).Row
    For x = LastRow To 1 Step -1
        If Application.WorksheetFunction.CountIf(Range("A1:A" & x), Range("A" & x).Text) > 1 Then
        Range("A" & x).EntireRow.Delete
      End If
  Next x
End Sub

这里是一个递归循环，以防万一你想要它：）

它实际上是 2 个过程，第一个排序列表，第二个删除重复

这些设置的方式，你会像这样使用它们.....

QuickSort MyArray, LBound(MyArray), UBOUND(MyArray)
MyArray = RemoveDuplicatesBlanks_1DSorted(MyArray)

这些工作只为 1 维数组，我也有他们的 2 维数组，如果你需要那些。

我已经使用了很多次，它们非常快，比大多数方法快得多，所以如果你有大列表，它值得使用这些方法。

----附加信息----

ExtractArrayColumn 函数位于此代码下方....这里的代码是如何使用所有这些过程

Private sub RemoveDuplicate()
    Dim MyRangeArray As Variant, MyArray As Variant
    MyRangeArray = Range("A1:A100").Value
    MyArray = ExtractArrayColumn(MyRAngeArray,1)
    QuickSort MyArray, LBound(MyArray), UBOUND(MyArray)
    MyArray = RemoveDuplicatesBlanks_1DSorted(MyArray)
    Range("A1:A100").Value = MyArray
End Sub
Public Function ExtractArrayColumn(Array_Obj As Variant, Column_Index As Long) As Variant
    Dim TArr() As Variant
    Dim L1 As Long, H1 As Long
    Dim i As Long

    H1 = UBound(Array_Obj, 1)
    ReDim TArr(L1 To H1)
    For i = L1 To H1
        TArr(i) = Array_Obj(i, Column_Index)
    Next i
    ExtractArrayColumn = TArr
End Function
