[英]How do you remove text from a string in VBA Microsoft Excel
I want to trim a string in MS Excel each cell to 100 characters in a column with 500 cells. 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。
Starting with first cell, check if string length is or equal 100 characters. 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。 If the words are more than 100, then remove 1 word in the cell, then check again, if it's more than 100 remove another word until the string is less to 100. Then paste the less than 100 character string into the same cell replacing previous more than 100 character string. 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。
Then move to another cell and replete the previous step. 然后移到另一个单元格并补充上一步。
The words to be removed are in an array 要删除的单词在数组中
Here is my code so far 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
