I wrote this book in 2010, after which it never sold as many copies as it should have. For years I've thought about web-ifying (and free-ifying) it, since there's a lot of useful (and entertaining) information in it, but I never got around to it until now.
It's mostly based on Excel 2007, but (let's face it) Excel doesn't change all that much anymore, and my estimate is that approximately 98% of what I've written still applies to the latest version. I've
strikethroughed a few parts that don't. I spent a small amount of time trying to make the CSS attractive, but I'm not a web designer, and it shows.
If you find this useful and/or entertaining, I'd love to hear from you. You can email me at email@example.com, or find me on Twitter @joelgrus. If after this taste you want to buy a hard copy, it's available from Amazon.
Anyway, read it, enjoy it, recommend it to your friends!
