Sorry - no sample files for that book.
As I was writing the book, the development editor didn't believe that anyone would ever want to follow along with any of the examples in the book.
I will be more adamant about including sample files for Special Edition Using Excel 2010.
Some have asked if I could go back and provide files. However...since half of the Excel 2007 book was written using early beta versions, all of the files are useless. A file created in Beta 1 would have had to have been refreshed and saved in Beta 1R, Beta 2, Beta 2R, then the RTM version.
