Hi everyone,

I have a VBA code puzzle to solve.

I want to reverse an alphanumeric string, but reverse only letters and leave digits where they are.

So for example:
abc123dfg ---> gfd123cba
451ubno98p ---> 451ponb98u
egc88rtv972nq100 ---> qnv88trc972ge100

Do you have any ideas?
Probably I must use nested loop. I came with this idea, but it's not working perfectly:

Code:
Text = ThisWorkbook.Sheets(1).Range("L2")


lenght = Len(Text)


For x = 0 To lenght - 1
    signfromend = Mid(Text, (lenght - x), 1)
    If Not IsNumeric(signfromend) Then
        For y = x + 1 To lenght
            signfromstart = Mid(Text, y, 1)
            If Not IsNumeric(signfromstart) Then
                reversedText = reversedText & Mid(Text, (lenght - x), 1)
                Exit For
            Else
                reversedText = reversedText & signfromstart
                Exit For
            End If
            x = x + 1
        Next
    Else
        reversedText = reversedText & signfromend
    End If
Next
