Excel VBA：“将子例程更改为函数”，用于字符串转换

Question

通过我的工作以及复制其他人的工作，我拼凑了一个 Excel VBA Sub，它将包含（文本组）和（数字组）组的长串分隔成一个替换字符串，每个单独的组之间有空格；按照这个例子： • “123abc12aedsw2345der” • …应用选择 Sub() 然后变为： • “123 abc 12 aedsw 2345 der” 它根据“选择”转换原始单元格中的字符串，因此我当前保留原始单元格中更改后的数据 问题：我想将其更改为函数，其中转换后的数据将出现在函数单元格中，并保持原始单元格不变。我已经完成了数百个这样的功能，但我似乎无法让它作为一个独立的功能工作。在完成并工作的子例程下面，我尝试转换为独立函数以从工作表上的任何位置调用：

Sub SplitTextNumbersSelection()
Dim c As Range

'********** Inserts Space Before Number Groups ******************************
For n = 1 To 10
    For Each c In Selection
        c = InsertSpace(c.Text)
    Next
Next n
'****************Inserts Space Before Letter Groups ***********************
For n = 1 To 10
    For Each c In Selection
        c = InsertSpace2(c.Text)
    Next
Next n
'****************************************

End Sub

Function InsertSpace(str As String) As String
    With CreateObject("vbscript.regexp")
        .Pattern = "([a-z])(\d)"
        '.Pattern = "(\d)([a-z])"
        InsertSpace = .Replace(str, "$1 $2")
    End With
End Function

Function InsertSpace2(str As String) As String
    With CreateObject("vbscript.regexp")
        '.Pattern = "([a-z])(\d)"
        .Pattern = "(\d)([a-z])"
        InsertSpace2 = .Replace(str, "$1 $2")
    End With
End Function

简单一点：

Function PrepString(v As String)
    Dim rv As String, i As Long, c1, c2
    For i = 1 To Len(v) - 1
        c1 = Mid(v, i, 1)
        c2 = Mid(v, i + 1, 1)
        If (c1 Like "[a-z]" And c2 Like "[0-9]") Or _
           (c2 Like "[a-z]" And c1 Like "[0-9]") Then
            rv = rv & c1 & " "
        Else
            rv = rv & c1
        End If
    Next i
    PrepString = rv & Right(v, 1)
End Function
