Excel 2010: The Missing Manual offers a great guide to Excel 2010. Matthew MacDonald does three things quite well in this book: (1) covers the important features of Excel, (2) explains the features in a user-friendly way, and (3) makes the topic of using Excel interesting.
Excel 2010 has hundreds of features — this book focuses on the features that address common real-world situations, such as generating monthly financial reports and updating files with new data. MacDonald explains how to use Excel’s many features and functions in an easy-to-follow and non-technical manner. In addition, the author manages to keep this subject matter, which could prove dry and dense, interesting and engaging.
I am a long-time and regular user of Excel as well as the author of a book on building financial models with Microsoft Excel (Building Financial Models with Microsoft Excel: A Guide for Business Professionals (Wiley Finance)). This book (Excel 2010: The Missing Manual) is among the very best guides to the general use of Microsoft Excel that I have come across.
Recommended reading for users of Microsoft Excel 2010 — new Excel users and users migrating to Excel 2010 alike.
