If you're still building formulas the old way - one cell at a time, you're missing out on one of Excel's most powerful modern features: dynamic arrays.
These game-changing formulas allow you to write one formula and instantly fill a whole range, saving time and reducing errors.In this session, you'll learn what dynamic arrays are, how they differ from traditional formulas, and why they're a smarter, cleaner way to work with data. You'll see how functions like FILTER, UNIQUE, SORT, XLOOKUP, and SEQUENCE can simplify everything from data extraction to custom lists and lookup tasks, without resorting to clunky workarounds.
This is your chance to finally "think in arrays" and unlock a more intuitive, efficient way to build formulas in Excel. NOTE: Dynamic arrays are only available in Excel 365, 2021 and 2024
Why should you Attend: Still dragging formulas across columns? Still using clunky workarounds? Dynamic arrays eliminate the complexity and tedium of old-school formula-building. If you're looking for a cleaner, faster, more flexible way to build reports, perform lookups, and manipulate data, this session will help you break out of the traditional formula mindset and take advantage of Excel's modern capabilities.
