FEATURES
Features of Office 2021 for Windows
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.

Questions and answers
Is a direct installer available for Office 2021 for Windows?
Enabled downloads lead directly to verified installer files. — Use an enabled Download button for Windows to retrieve the matching English installer directly from the official publisher. Check the selected product and license before installation. Account, store and guide pages are not offered as downloads.
Is Office 2021 x86 available for PCs with 32-bit add-ins?
x86 is not available for every edition. — For example, Standard LTSC x86 and Professional x86 are available, but there is no separate Home & Student x86 on this page.
Which Office 2021 should I download for Windows: Home & Business or LTSC Standard?
Check the license type before choosing a file. — Home & Business is a separate purchase, while LTSC Standard is intended for volume licensing; matching years and languages do not make them interchangeable.
How do I choose the right Office 2021 for Windows option for Windows?
Use the installation path for your actual device and license. — Check the official system requirements, platform, edition and architecture before installation. On Windows, confirm compatibility with existing Office apps and add-ins. Windows installation media cannot be installed on macOS or mobile devices.
What should I check before installing Office 2021 for Windows?
Back up your documents and confirm the release’s requirements and support status. — This release is no longer supported. Use it only where a licensed legacy workflow requires it, keep backups and plan a move to supported software.
