Have you tried adding an apostrophe before the ISBN in Excel? (E.g., instead of 
9783161484100, write '9783161484100 - note the leading apostrophe). As far as I 
know, this trick forces Excel to treat the number as a string (and it won't 
include the apostrophe), so it will be saved correctly, without any scientific 
notation.
