I am an intermediate Excel user. I was looking for a book that could be used as a quick reference. This book is the best book I have ever read. I learned a great deal about hidden capabilities of Microsoft Excel. If you work with excel a lot, especially for analyzing data, this is the book for you. Every chapter introduces a new excel technique. Explanations are straight forward and easy to understand. Included CD has all the examples, both solved and unsolved.

I analyze a lot of data in my job everyday. Techniques I learned from this book help me everyday in getting my work done faster.

Excellent...It really help me to better understand the data analysis with many differents case scenarios...exercises...its for everyone.

I had to use for a college class, but great speed in shipping.

I am an intermediate to advanced Excel user, so my review may reflect that level. As others have said, it looks like MS rushed this book to the market, evidenced by so many errata, which can be disappointing especially when the solution is wrong. On the other hand, there are some very interesting and genuine uses of various Excel functions to solve business problems.
I wouldn't recommend this book for beginners. If you're trying to learn Excel, this is not the book. It is not a book to teach excel, but a book to teach you what you can do with Excel to solve everyday problems, given you're familiar with the mechanics of excel.
I would recommend it with these caveats. And getting Walkenbach's book on Excel functions along with this would be very helpful in my opinion. Best of luck in your endeavors.

I have read many books in excel, but this book is really the most beneficial and excellent book I've used in my life. It is full with practical not theoritical examples. and you can benefit form it in your work.

Overall, I like this book, even though it is somewhat confusing, both in scope and in the target audience.
The techniques of "naming the range" or writing the "if" formula are certainly targeted for beginners, but most of statistical tools are normally used by more advanced users.
The worst thing, though, is that the book is full of errors, both typos and mistakes in problem solutions on the disk. I consider myself an intermediate user, so finding an error in "instructor solution" was more like an additional challenge for me, but for the beginner this could be very frustrating.
On the positive side - I really liked the idea of problems in the end of each chapter; so many books just give you the theory and then you do not know how to solve a real life problem. For most of chapters, I knew the tools, but still had to spend time figuring out the best way to implement it for problem solving.
Very practical book, good for an intermediate users. Just be aware of the typos !

Product was in good condition and it arrived in a timely fashion. If the need arises I will purchase items from this vendor again, no questions asked.

JUST GREAT!
If you are good in excel and want to learn some cool new techniques and features to help you in your business analysis, this is the book for you.

The author has used simple examples to drive home the techniques and tools of business modeling. It definitely helps to save time and effort and helps you build efficient business analysis tools with ease.

The author is very knowledgeable in statistics and optimization and shows how to develop models for different applications. He also explains in detail on how to use MS Solver which is really cool!

This book is aimed at a level slightly higher than the total beginner. On page one, for instance he assumes that you understand the statement SUM(A5000:A5049) means. Then he points out that writing SUM(USSales) would make it easier to understand. He then describes how to name a range of cells -- Not exactly what I'd call advanced, but certainly above novice.

The first third, or so, of the book is on these kinds of slightly advanced procedures that you could get out of several Excell books. After that he kind of turns the approach around to things like "Estimating a Demand Curve." This is looking for what you want to do rather than just looking at a technique within Excell.

Many of his chapters have fairly sophisticated subjects, "Incorporating Qualitative Factors into Multiple Regression." In this chapter he then looks at multiple factors that might go into predicting things like predicting sales, predicting the Presidential race - with fairly surprising results.

In a couple of chapters he has a bit of fun, i.e. Chapter 73 is "Picking Your Fantasy Football Team."

Excell is quite a powerful package. It can be used for a lot of things beyond just filling out an expense account. In this book a lot of non traditional uses are described in a very light but informative manner. It is a very well done book.
