I won this book in a First Reads contest.
It will take readers more than 30 minutes to complete this book, even if they are experienced in Excel or in Google Spreadsheets. It takes more than 30 minutes just to read the book, without following the tutorial.
This book teaches readers the basics on the use of spreadsheet programs. Unlike many other tutorial books, this book is applicable to more than one version of Excel, and is also applicable to Google Spreadsheets. The author uses a single example throughout the book in order to demonstrate spreadsheet concepts. The tutorial is clearly written, and there are many pictures to guide the reader.
Readers should be aware of a few things.
It is very hard to keep the paperback edition open while following the author's instructions.
As specified in the title, this book teaches the basics of Excel, so do not expect to become an instant expert. However, the basics are taught very clearly.
In a few places in the book, it is clear that the author edited the instructions, causing a mismatch between the instructions and the images that accompany them.
It seems that the author assumes some basic knowledge. For example, in one location, the instructions mention that the reader should save the spreadsheet, without showing the reader how this can be accomplished.
Despite these issues, the tutorials are clear and interesting, even though they involve more than 30 minutes of effort.
