New for Office 365 customers, one single formula sitting in one single cell can return many results. Those extra results will spill into adjacent cells. This is a major change to the calculation engine in Excel. When you first hear of this feature, you might think it is about SORT, FILTER, UNIQUE, SORTBY, SEQUENCE, RANDARRAY, and SINGLE. But dynamic arrays make every Excel calculation function more powerful. Pass a SEQUENCE to another function and Excel will Lift the function to return many results. In this book, you will learn new terms such as Lifting, Broadcasting, Pairwise Lifting, Array Truncation, and why Implicit Intersection was the culprit in making the old Ctrl+Shift+Enter formulas so hard. Plus, you will never need to press Ctrl+Shift+Enter again.

  • Introduction

    • What about Implicit Intersection?
  2. SORT Function
    • Simple Sort with one argument
    • Sort by Two or more columns in the Results

    • Using SEQUENCE Inside Of Another Function
  8. RANDARRAY Function
    • Generating an Array of RAND() with RANDARRAY()
    • Simulating RANDBETWEEN
    • Using RANDARRAY for Modeling and Simulation
  9. Why CSE Array Formulas Were So Hard - it is Implicit Intersection
    • A Quick Glossary For This Chapter
    • Legacy Excel Used Arrays Far More Often Than We Realized
    • Explaining Implicit Intersection
    • Breaking Implicit Intersection
    • Lifting When A Scalar Is Expected, but an Array is Provided
    • Truncating Arrays
    • Using a Wrapper Function in Legacy Excel
    • Preventing Implicit Intersection With Ctrl+Shift+Enter
    • From Lifting to Pairwise Lifting
    • Broadcasting Makes All Arrays the Same Size
    • Here is a simple Broadcasting example
    • How Does Lifting, Broadcasting, Truncate Arrays, and Implicit Intersection Affect Dynamic Arrays?
