John Walkenbach comments on the new Excel: “I’ve been using Excel for over 15 years, and Excel 2007 is by far the most significant upgrade ever. For starters, we've got a new user interface, new open file formats, a larger worksheet grid, better use of memory and CPUs, new functions, and more templates. Dig a bit deeper and you'll find worksheet tables, 100 levels of undo, easier formula construction, better-looking charts, unlimited color choices, SmartArt, a handy page layout view, new conditional formatting options, new collaboration features, a very useful compatibility checker, workbook themes -- and even ‘skins’ so you can change the look of the entire program.”
To get up to speed on all the new features and to take advantage of the new power in Excel 2007, you need advice from the master. With 'Mr. Spreadsheet’s Excel 2007 Library', all the information you need is available in one package.
