### Command The Power of the 'Array Formula' in Microsoft Excel!

Array Formulas are a powerful tool in Excel. An Array Formula works with a series of Data Values instead of a single Value. Excel Array Formulas are mysterious, even to people who use Excel 40 hours a week. Start with the secret keystroke that must be used to finish an Array Formula: Ctrl+Shift+Enter. Then, you have to know which functions will work with Arrays and which will not. Once you get a grasp on Array Formulas, you will find they solve problems that regular Excel Formulas can not solve, or would require hundreds of thousands of regular Formulas.

Although elusive, Array Formulas can be used to solve everyday Excel problems. If you need to figure out how many times your birthday fell on a Friday, an Array Formula can solve that. If you need to return a unique list of sales reps from a Database, an Array Formula can solve that.

### How does this book approach Array Formulas?

This book systematically lists the aspects, elements and guidelines for array formulas. Array formulas can be insanely difficult. But there are times when an array formula is the only way to accomplish a task. Array formulas can beat filtering, sorting and pivot tables because array formulas will automatically update when the input cells change.

### Why should you read this book:

- You love Excel magic and wizardry. Your idea of fun is making Excel do the impossible with a formula.
- You know how to create formulas and want to take the next leap in Excel, into the upper echelon of creating advanced formulas.
- You cringe when a co-worker sends a workbook with formulas wrapped in curly braces.
- You have heard about array formulas and know that in some situations, they are the most efficient solution, but you have no idea how to create them.
- You use array formulas and are aware of some of the drawbacks they present (such as slow formula calculation time), and you would like to learn how to create more efficient array formulas.

Note

The DVD 'Ctrl+Shift+Enter: Mastering Excel Array Formulas' is a separate product from this book. The two products cover the same broad topics related to creating efficient array formulas. However, the video has kinetic visuals of how array formulas work and less detail than the book. The book has a more complete story and systematic presentation of array formulas. If you really want to master array formulas, study both the book and the DVD.
