FEATURES

Microsoft Office 2021 features

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 Microsoft Office 2021?

Enabled downloads lead directly to verified installer files. — Use an enabled Download button for Mac, 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.

Why does Office 2021 Standard have x86 and x64 ISOs?

These are separate LTSC Standard images. — Choose the architecture before downloading and check the volume license type: LTSC is not the same as a retail home edition.

How do I install Microsoft Office 2021 in English?

Choose the language through the official installation or app settings. — Choose English in the available installer or application settings. Display and proofing languages can be configured separately. Language settings for an existing licensed installation do not establish that a new installer download is available.

How do I choose the right Microsoft Office 2021 option for your device?

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 Microsoft Office 2021?

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.
