How to change "01-","02-", to A, B in Excel 2016 custom function?

I had this question after viewing How to add a parameter to this custom function for the number of columns?.

Function CombineText(rg As Range) As String
    Dim col As Integer
    If rg.Rows.Count = 1 Then
        For col = 1 To rg.Columns.Count
            If rg.Cells(1, col) = "" Then
                CombineText = CombineText & "00"
            Else
                CombineText = CombineText & Left(rg.Cells(1, col), 2)
            End If
            If col < rg.Columns.Count Then
                CombineText = CombineText & "-"
            End If
        Next col
    End If
End Function

In this function, the first three characters of cells are in the format "01-", "02-", etc. is picked up from cells from a number of columns.  I would now like to convert the "01-" to A, "02-" to B, etc.  There are no numbers above 26.  If a cell is blank, I would like its value to "X".

So you just want the result to be A-B-C-D-E, etc, that's all, no data from the cells themselves???

If it needs to be sensitive to what the left three characters then try this...

Function CombineTextA(rg As Range) As String
    Dim col As Integer
    Dim txt As String
    If rg.Rows.Count = 1 Then
        For col = 1 To rg.Columns.Count
            If rg.Cells(1, col) = "" Then
                txt = "0"
            Else
                txt = Left(rg.Cells(1, col), 2)
            End If
            txt = Chr(Asc("A") + CInt(txt) - 1)
            If col = 1 Then
                CombineTextA = txt
            Else
                CombineTextA = CombineTextA & "-" & txt
            End If
        Next col
    End If
End Function
