将此函数插入​​Visual Basic编辑器中的新模块：

Insert this function into a new module in the Visual Basic Editor:

Function AlphaNumericOnly(strSource As String) As String
    Dim i As Integer
    Dim strResult As String

    For i = 1 To Len(strSource)
        Select Case Asc(Mid(strSource, i, 1))
            Case 48 To 57, 65 To 90, 97 To 122: 'include 32 if you want to include space
                strResult = strResult & Mid(strSource, i, 1)
        End Select
    Next
    AlphaNumericOnly = strResult
End Function

现在您可以将其用作用户定义函数，即如果您的数据位于单元格 A1 中，请将此公式放在空单元格 = AlphaNumericOnly（A1）。

Now you can use this as a User Define Function, i.e. if your data is in cell A1, place this formula in an empty cell =AlphaNumericOnly(A1).

如果要直接转换大范围，即替换所有非字母数字字符而不离开源代码，可以使用另一个VBA例程：

If you want to convert a large range directly, i.e. replace all the non-alphanumeric characters without leaving the source, you can do this with another VBA routine:

Sub CleanAll()
    Dim rng As Range

    For Each rng In Sheets("Sheet1").Range("A1:K1500").Cells 'adjust sheetname and range accordingly
        rng.Value = AlphaNumericOnly(rng.Value)
    Next
End Sub

只需将此子放在同一个模块中并执行它。请注意，这将取代范围内的任何公式。

Simply place this sub in the same module and execute it. Be aware though, that this will replace any formulas in the range.
