Up Up and Array!: Dynamic Array Formulas for Excel 365 and Beyond - Softcover

Über die Autorin bzw. den Autor

Abbott Ira Katz is a native New Yorker living in London, He has been teaching Excel for 25 years, exploring the application with learners on both sides of the Atlantic. He has authored two Apress books on Excel–Microsoft Excel 2010, and Excel 2010 Made Simple, he wrote the spreadsheetjournalism.com blog, and has contributed Excel-themed pieces to datajournalism.com, the Irish Tech News, datadrivenjournalism.net, and the baseball journal By the Numbers. His work with spreadsheets has been cited by the Guardian, the Wall Street Journal, the Freakonomic blog, and the Excel expert Chandoo, and he gave an Excel-driven, five-session workshop on Data Stories at Sciences Po University in Paris in 2018. Abbott has a doctorate in sociology from SUNY Stony Brook. The idea for a book on dynamic array functions springs from a sense that the take-up of these potent tools remains small, and that large numbers of spreadsheet users remain unaware of their capacity for facilitatinga myriad of wide-ranging tasks.

Understand the power of dynamic arrays: a single formula can generate new and vastly more efficient spreadsheet possibilities. This book introduces spreadsheet users to dynamic array functions in Microsoft Excel 365, defines and details the distinctive ways in which they work, and shows how they can be applied to a wide swath of data-analytic tasks.

While array formulas and functions have long held a place in the spreadsheet toolbox (although, for many of us, shunted to an obscure corner), the dynamic array engine offers a more user-friendly and intelligible set of means for manipulating spreadsheet data in the array mode. The single-formula, multi-cell capability of dynamic arrays has been extended to nearly all existing spreadsheet functions, offering a new, default way of working. As a result, many tasks can now be executed with dynamic arrays without having to resort to the new functions at all.

After defining arrays and dynamic array formulas, this book helps you examine the dynamic array property of lifting and how it impacts the formulas, including those written with existing functions. Plenty of illustrations and formulas along the way help you get comfortable using them. From there, you will learn Excel 365’s new dynamic functions, including the 14 currently in rollout, each accompanied by instructive examples. In many cases, the examples demonstrate how the new functions can work with long-available functions, such as MID, IF, COUNTIF, etc., which now also boast dynamic array functionality.
