If you want to learn Excel quickly and thoroughly, without ever being patronized or bewildered, read Microsoft Office Excel 2007 Step by Step.
We're huge fans of Microsoft's Step-by-Step series. These hands-on software tutorials borrow the best ideas from decades of computer books and add some great innovations of their own. They're a pleasure to use. Even small details are handled well: for example, each task's instructions are formatted and color-coded for easier reading. At a higher level, these books -- and the Excel guide in particular -- are superbly organized and edited. You can learn systematically, end-to-end, or learn just what you need today.
Oh, and if you're worried about the Ribbon, the controversial centerpiece of Excel's new interface, don't. This book will make you right at home. There's even a full-color poster for handy reference. Bill Camarda, from the March 2007 Read Only
