Dynamic Arrays Formulas in Excel 2021 and Microsoft 365

Author: David H. Ringstrom

Since its inception, Excel’s recalculation engine has never been revamped. Excel expert David Ringstrom, CPA, introduces course participants to an entirely new class of worksheet functions known as dynamic arrays. Available only to Office 365 subscribers, dynamic arrays recalculate traditional formulas faster. They also eliminate the need to use menu commands to sort, filter, and/or remove duplicates from a list of data. You can create formulas that resize themselves automatically, including an amortization table that expands into additional rows when a loan term increases or contracts when a loan term is shortened.

David demonstrates every technique at least twice: first, on a PowerPoint slide with numbered steps, and second, in the subscription-based Microsoft 365 (formerly Office 365) version of Excel. David draws your attention to any differences in the older versions of Excel (2021, 2019, 2016 and earlier) during the course as well as in his detailed handouts. David also provides an Excel workbook that includes most of the examples he uses during the course.

Microsoft 365 is a subscription-based product that provides new feature updates as often as monthly. Conversely, the perpetual licensed versions of Excel have feature sets that don't change. Perpetual licensed versions have year numbers, such as Excel 2021, Excel 2019, and so on.
