Hi it is not safe to get the binary content by using 
http://{guvnor_url}/rest/packages/{package}/assets/{xls_name}/source. As 
the Guvnor has no idea what charset encoding is used by that binary 
file. When Guvnor converts the binary to a String representation, it can 
only use the platform default charset. If this is the different encoding 
than the original one, then your file will be corrupted.
Make sure you use 
http://{guvnor_url}/rest/packages/{package}/assets/{xls_name}/binary 
instead to retrieve the binary content.

Cheers,
Jervis
