O
ur deepest thanks to the professionals at John Wiley & Sons for all the hours of work
put into bringing this book to life. Thanks also to Jordan Goldmeier, Joyce Nielsen,
Doug Holland, and Guy Hart-Davis for suggesting numerous improvements to the
examples and text in this book. A special thank-you goes out to our families for putting

Walkenbach for his many years of work on the previous editions of this book. His efforts
in curating Excel knowledge have been instrumental, not only in helping millions of Excel
