What's new in Office 2021 Pro Plus compared with previous versions

Office 2021 Pro Plus brings concrete, measurable improvements over Office 2019 and Office 2016:

In Excel, dynamic arrays now let you write formulas that automatically return multiple results across several adjacent cells, removing the need for complex array formulas. The new XLOOKUP function is a powerful replacement for VLOOKUP, allowing lookups in both directions with a default value when no match is found.

In Word, Line Focus mode improves concentration by displaying only one, three or five lines of text at a time, reducing visual distractions. The intelligent Editor suggests not only spelling corrections but also stylistic rewrites to improve the clarity of your writing.

In PowerPoint, slide show recording has been completely redesigned with a multi-view interface that makes it easier to create recorded presentations and video training. The Replay tool lets you review ink annotations and transitions while recording.
