'also convert Empty values as well, for use with Variants:

Public Function Clean(ByVal varData As Variant) As String
If IsNull(varData) Then
Clean = ""
ElseIf IsEmpty(varData) Then
Clean = ""

Clean = CStr(varData)
End If
End Function

columns has a Null value. For most purposes, I'd rather have the value
as an empty string anyway. Rather than code for that each time I access
a column, I've written a function called Clean that turns Null values into
empty strings. I call it like this:
