This is not a book for beginning Excel users. If you have absolutely no experience with Excel, this is probably not the best book for you-unless you're one of a rare breed who can learn a new software product almost instantaneously.
To get the most out of this book, you should have some background using Excel. Specifically, I assume that you know how to
Create workbooks, insert sheets, save files, and other basic tasks
Navigate through a workbook
Use the Excel 2007 ribbon and dialog boxes
Use basic Windows features, such as file management and copy and paste techniques
