我想检查excel中相应单元格中文本的相似性

我的excel工作表中有一个数据集，每个单元格中的数据是一组以“；”分隔的数字

预期结果是在第二个单元格中，所有四个数字都在两列（G和H）中，但顺序不同。在下一行中，顺序相同。那么，有没有办法检查相似性呢

我试过使用下面的代码，但它似乎只突出显示（红色）前几个字符

代码是：

      xTxt = ActiveWindow.RangeSelection.AddressLocal
    Else
      xTxt = ActiveSheet.UsedRange.AddressLocal
    End If

    Set xRg1 = Application.InputBox("Range A:", "Similarity finder", xTxt, , , , , 8)
    If xRg1 Is Nothing Then Exit Sub
    If xRg1.Columns.Count > 1 Or xRg1.Areas.Count > 1 Then
        MsgBox "Multiple ranges or columns have been selected ", vbInformation, "Similarity finder"
        GoTo lOne
    End If

    Set xRg2 = Application.InputBox("Range B:", "Similarity finder", "", , , , , 8)
    If xRg2 Is Nothing Then Exit Sub
    If xRg2.Columns.Count > 1 Or xRg2.Areas.Count > 1 Then
        MsgBox "Multiple ranges or columns have been selected ", vbInformation, "Similarity finder"
        GoTo lTwo
    End If
    If xRg1.CountLarge <> xRg2.CountLarge Then

    xRg2.Font.ColorIndex = xlAutomatic
    For I = 1 To xRg1.Count
        Set xCell1 = xRg1.Cells(I)
        Set xCell2 = xRg2.Cells(I)
        If xCell1.Value2 = xCell2.Value2 Then
            If Not xDiffs Then xCell2.Font.Color = vbRed
        Else
            xLen = Len(xCell1.Value2)
            For J = 1 To xLen
                If Not xCell1.Characters(J, 1).Text = xCell2.Characters(J, 1).Text Then Exit For
            Next J
            If Not xDiffs Then
                If J <= Len(xCell2.Value2) And J > 1 Then
                    xCell2.Characters(1, J - 1).Font.Color = vbRed
                End If
            Else
                If J <= Len(xCell2.Value2) Then

如果J一种方法是使用第一列创建正则表达式，并对第二列应用它

使用regex的一个优点是，返回的数据之一是匹配的开始和长度——非常适合寻址range对象的characters属性

我使用了早期绑定（请参阅代码注释中要设置的引用），但是如果必须的话，可以使用后期绑定

我也有A列和B列中的数据，但您可以使用定义数据位置的代码部分来更改这些数据

您不需要在出现错误时使用任何
代码。编写代码来处理任何可预见的错误要好得多。我没有做任何错误检查，这可能需要添加

如果速度是一个问题，可以进行其他各种修改

构造的正则表达式将具有

\b（？：nnn | nnn | nnn | nnn）\b

这意味着


匹配单词边界
匹配任何管道分隔的子字符串
匹配另一个单词边界
