Although this book is divided into chapters, as described in the following section, you can use it in a variety of different ways. One approach is to think of the book as a toolbox and start by becoming familiar with the tools in each chapter. Then, when a need arises or a problem occurs, you can simply use the right tool for the job. Or, you might decide to browse through the book or read it from cover to cover, studying the procedures and scripts to learn more about Excel. Some of the hacks are helpful in this area because they contain tutorials about complex subjects or well-documented scripts. You also might pick one chapter and see what you find useful to your current situation or what you might find helpful in the future.
