Reading more than 255 characters from excel

Question

I am trying to read a sheet data from excel (tried both oldedb and odbc) and found out that there is 255 characters limit. I tried using Range object as suggested

Answer 1

Since the issue is with the Jet Provider, why not try the Microsoft Excel Driver listed under ODBC connctions.
