[SOLVED] Excel VBA: "Change a Subroutine into a Function", for String Conversion


Through my work, and copying others, I have cobbled together a Excel VBA Sub that separates a long sting with groups of (text groups) and (number groups) into a replacement string with spaces in between each seperate group; as per this example:
• …Apply selection Sub() then becomes:
“123 abc 12 aedsw 2345 der”
It converts the string in its original cell as per the “selection”, so I am currently left with the altered data in is original cell
PROBLEM: I would like to change this into a FUNCTION where the transformed data would appear in the Function cell and leave the original cell intact. I have done hundreds of these but I cannot seem to get this to work as an independent FUNCTION. Below the finished and working Sub Routine I am trying to convert to an independent function to call from anywhere on the worksheet:

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


Bit simpler:

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 & " "
            rv = rv & c1
        End If
    Next i
    PrepString = rv & Right(v, 1)
End Function
