If you have reached this part of the book, I would assume you have read eight chapters and have quite a good view of what you can do with Google Apps Script. However, you have to know that all this is just a part of it—a small part actually.

I did present a few examples of data exchange between different Google services (docs and spreadsheets, Gmail and docs, and so on), but there is definitely much more to explore. This book could easily have over 500 pages without too much effort, but as the title states, this book just provides a few samples to help you to get started.
