Dynamic array functions in Excel allow users to perform calculations on multiple cells at once, saving time and increasing efficiency. This allows users to build more robust spreadsheets, in less time, with fewer errors. Follow along with Excel MVP Oz du Soleil as he walks you through Excel’s calculation engine and demonstrates how to make the most of dynamic array functions. He walks through all the key functions—including UNIQUE, SORT, SORTBY, SEQUENCE, FILTER, and newer functions like TOCOL and CHOOSECOLS—showing practical, real-world uses for each one. Plus, learn how to use the spilled range operator (#) to reference a dynamic spill range. Oz concludes the course with a series of challenges so viewers can practice and master dynamic arrays.
