It is available as a platform-specific purchase for Windows or Mac, so choose the correct edition at checkout.
The suite includes updated features across apps: Word with improved translation and handwriting input on Windows, Excel with dynamic arrays and XLOOKUP, PowerPoint with new animations and record/replay on Windows, and Outlook with integrated translation and Focused Inbox.
