我开发了以下代码来比较A列和D列中的两个单元格(字符串),如果找到部分匹配,则记下相应B单元格中的D单元格值。

Sub CompareAndGuess()
Dim strLen, aux As Integer
Dim max1, max2 As Long
Dim str As String

Range("A1").Select
Selection.End(xlDown).Select
max1 = ActiveCell.Row
Range("D1").Select
Selection.End(xlDown).Select
max2 = ActiveCell.Row

For a = 2 To max1
    str = Cells(a, 1)
    str = StrConv(str, vbUpperCase)
    strLen = Len(str)
    aux = strLen

    For l = 3 To strLen
         For d = 2 To max2
             If Cells(d, 4) = Left(str, aux) Then
                Cells(a, 2) = Cells(d, 4)
                Exit For
            ElseIf Cells(d, 4) = Right(str, aux) Then
                Cells(a, 2) = Cells(d, 4)
                Exit For
            End If
        Next d

        aux = aux - 1
        If Cells(a, 2) <> "" Then
            Exit For
        End If
    Next l
     Cells(a, 2).Select
Next a
End Sub

任何人都可以帮我找到问题所在,因为当我运行代码时,代码只猜测50行中的一行,而它应该匹配至少40行左右。

拜托,我真的找不到那里的错误。如果您愿意,请随意为我的问题提出另一种解决方案。

我正在分析的数据样本是: 使用错别字的名字: -

我找到了在每个人的帮助下做到这一点的正确方法。 这是:

        If InStr(1, Cells(d, 4), Left(str, aux)) = 1 Then
            Cells(a, 2) = Cells(d, 4)
            Exit For
        ElseIf InStr(Cells(d, 4), Right(str, aux)) + strLen - aux = strLen Then
            Cells(a, 2) = Cells(d, 4)
            Exit For
        End If

我很高兴你自己使用InStr功能解决了这个问题。您的代码运行不正常的原因是因为您将名称的缩短版本与全长版本进行比较。使用以下代码修改您的早期代码会发现更多匹配。

            If Left(Cells(d, 4), aux) = Left(str, aux) Then
                Cells(a, 2) = Cells(d, 4)
                Exit For
            ElseIf Right(Cells(d, 4), aux) = Right(str, aux) Then
                Cells(a, 2) = Cells(d, 4)
                Exit For
            End If

这绝对是 UNTESTED

明天我会改写,然后清理它,但这是真正知道你匹配正确单词的基本方法。这可能需要更长的时间,我会明天加快速度但现在这是测试有效性的方法的壁橱方式

'Go through all possibly typod words
For each rngTestCell in Range("yourlist")

   'For each possibly typod word test if against every correct value
    For each rngCorrectedValue in Range("ListOfCorrectValues")

        'start by testing length to weed out most values quick
        'Test any words that are within 3 letters of each other, can be less
        'could add a tet for first and last letters match also before starting 
        'to match every letter also, just a top level weeding of words
        If (Len(rngTestCell) - Len(rngCorrectedValue)) < 3 Then

           'loop each letter in the words for match keep a record of how many are matched
           for i = 1 to Len(rngTestCell)

                If rngTestCell.Character(i,1) = rngCorrectedValue.Characters(i,1) Then
                     NumberOfMatches = NumberOfMatches + 1
                End If

            next i

            'if enough of the letters match replace the word, this will need updating because
            'i feel using a ratio of more then 10% of the words match then replace
            'but for now if more then 2 letters don't match then it isn't a match
            If (Len(rngTestCell) - NumberOfMatches) > 2 Then 'Less then 2 letters are different
                rngTestCell.Offset(,1).Value = rngCorrectedValue.Value
                Exit Loop
            End If

        End If

    Next rngCorrectedValues

Next rngTestCell
