An alternative solution is to add or change the setting TypeGuessRows in the registry. By setting its value to 0, the complete document will be scanned.

Unfortunately, the settings may be found on various locations in the registry, depending on the which libraries and versions of them you have installed.

For instance: [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Jet\4.0\Engines\Excel] "TypeGuessRows"=dword:00000000

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\14.0\Access Connectivity Engine\Engines\Excel] "TypeGuessRows"=dword:00000000

This will also prevent truncation of textual data longer than 255 characters. This happens if you have a number for TypeGuessRows larger than 0 and the first text longer than 255 characters occurs beyond that number.
