How to prevent Excel from turning 1- 3 into a date

I have a file with a column that contains numbers with some dashes and spaces that display as text. I have a macro that takes an entry like 1-3 and converts it to 1,2,3. However if the cell contains a space before or after the dash, the macro converts it to  03-Jan. How do I trick Excel into reading "- " as a text hyphen and produce the result 1,2,3? I tried adding a line that removes the spaces but as soon as you do that the cell turns to 03-Jan.

Thanks!

You can also use this User Defined Function. If the data was in A! then
=Spread(A1)

Function Spread(c As Range) As String
Dim lngNum As Long
Dim strParts() As String

strParts = Split(c, " - ")

If UBound(strParts) <> 2 Then
    Spread = "#Value!"
    Exit Function
End If
For lngNum = strParts(0) To strParts(1)
    If lngNum = strParts(1) Then
        Spread = Spread & lngNum
    Else
        Spread = Spread & lngNum & ","
    End If
Next
End Function
