FEATURES
Office 2021 features: Home & Business
XLOOKUP in Excel
Find values in a range and return the corresponding result from another range. This is useful for looking up prices in a reference table or matching records by product code.
Word dark document
Switch the document canvas to dark mode. Choose a page display you find comfortable while working; the canvas color does not require changing the printed document's formatting.
PowerPoint ink animation
Replay strokes and annotations in a presentation with Ink Replay. Reveal your explanation gradually: viewers see the sequence of annotations, not just the finished drawing.
ODF 1.3 format
Work with the updated OpenDocument format in Word, Excel, and PowerPoint. This helps you exchange files with programs that support OpenDocument. Check complex formatting separately after conversion.
Excel dynamic arrays
Get a set of results from one formula: filter rows with FILTER, sort with SORT and return unique values with UNIQUE. The result size changes with the data.
Clearer formulas with LET
Assign names to intermediate results within an Excel formula. This makes complex calculations easier to read and lets you reuse parts without duplicating expressions.
Position lookup using XMATCH
Find an item's position in an Excel range with an exact or approximate match. Use the result in more complex data lookup and matching formulas.
Availability check
Check that your document, Excel workbook, or presentation is accessible to users of assistive technologies. Fix any issues found before sharing the materials.
Outlook email and calendar
The Home & Business edition adds Outlook to Word, Excel, PowerPoint and OneNote. The email app helps manage work correspondence and plan meetings alongside document preparation.
