Mike Girvin’s new book about array formulas called “Ctrl+Shift+Enter” is something you won’t want to miss if you are proficient with Excel formulas and want to get to the next step. Amazon introduces it like this:

Designed with Excel gurus in mind, this handbook outlines how to create formulas that can be used to solve everyday problems with a series of data values that standard Excel formulas cannot or would be too arduous to attempt. Beginning with an introduction to array formulas, this manual examines topics such as how they differ from ordinary formulas, the benefits and drawbacks of their use, functions that can and cannot handle array calculations, and array constants and functions.
