Just another option:

Function IsRange(s As String) As Boolean
On Error Resume Next
IsRange = Range(s).Address < vbNullString
End Function

I need a simple Boolean function that, given a string as an input, will
return TRUE if the string can be converted directly into a range,
otherwise
FALSE. For example:

A1
Sheet3!F20
[Book1.xls]Sheet1!$B$2

should all return TRUE, but:

A1+A2
A1+1

should all return FALSE

Thanks in advance
