如何从VBA Microsoft Excel中的字符串中删除文本

Question

我想在MS Excel中将每个单元格中的字符串修剪为包含500个单元格的列中的100个字符。

从第一个单元格开始，检查字符串长度是否等于或等于100个字符。 如果单词多于100，则删除单元格中的1个单词，然后再次检查，如果单词多于100，则删除另一个单词，直到字符串小于100。然后将少于100个字符串粘贴到同一单元格中，以替换先前的单词。超过100个字符串。

然后移到另一个单元格并补充上一步。

要删除的单词在数组中

到目前为止，这是我的代码

Sub RemoveWords()
Dim i As Long
Dim cellValue As String
Dim stringLenth As Long
Dim myString As String
Dim words() As Variant
words = Array("Many", "specific ", "Huawei", "tend", "Motorolla", "Apple")

myString = "Biggest problem with many phone reviews from non-tech specific publications is that its reviewers tend to judge the phones in a vacuum"
For i = 1 To 13
cellValue = Cells(i, 4).Value
        If Not IsEmpty(cellValue) Then
            stringLength = Len(cellValue)
            ' test if string is less than 100
            If stringLength > 100 Then
                Call replaceWords(cellValue, stringLength, words)
            Else
               ' MsgBox "less than 100 "
            End If
        End If          
    Next i

End Sub

Public Sub replaceWords(cellValue, stringLength, words)
    Dim wordToRemove As Variant
    Dim i As Long
    Dim endString As String
    Dim cellPosition As Variant

    i = 0

    If stringLength > 100 Then

        For Each wordToRemove In words
            If InStr(1, UCase(cellValue), UCase(wordToRemove )) = 1 Then
            MsgBox "worked word found" & " -- " & cellValue & " -- " & key
            Else
            Debug.Print "Nothing worked" & " -- " & cellValue & " -- " & key

            End If
        Next wordToRemove 
     Else
     MsgBox "less than 100 "
    End If

End Sub

Sub NonKeyWords()
' remove non key words
'

Dim i As Long
Dim cellValue As String
Dim stringLenth As Long
Dim wordToRemove  As Variant
Dim words() As Variant
Dim item As Variant

' assign non-key words to array
words = words = Array("Many", "specific ", "Huawei", "tend", "Motorolla", "Apple")

' loop though all cells in column D
For i = 2 To 2000
cellValue = Cells(i, 4).Value
    If Not IsEmpty(cellValue) Then
        ' test if string is less than 100
        If Len(cellValue) > 100 Then
        'Debug.Print "BEFORE REMOVING: " & cellValue
            Call replaceWords(cellValue, words, i)
        Else
           ' MsgBox "less than 100"
        End If
    End If
Next i

End Sub

Public Sub replaceWords(cellValue, words, i)

If Len(cellValue) > 100 Then

        For Each wordsToDelete In words
           If Len(cellValue) > 100 Then
            cellValue = Replace(cellValue, wordsToDelete, "")
            'Debug.Print cellValue
            Debug.Print "String length after removal = " & Len(cellValue)
            Debug.Print "remove another word................"
            'cells(i, 4).ClearContents
            Cells(i, 4).Value = cellValue
            Else
            'exit
            End If
        Next
 Else
    Debug.Print "SAVE: " & cellValue

End If

End Sub
