In the United States, Microsoft Office is so entrenched that .docx and .xlsx are the de facto standard for business, schools, and government. But you have real choices, including excellent free suites that read and write those exact formats. Whether you should pay comes down to how deeply you live in Microsoft's ecosystem.
Microsoft 365 is sold as a USD subscription (monthly or annual) and bundles the desktop Office apps with 1TB of OneDrive storage and Outlook. There's also a free Office for the Web. On the free side, LibreOffice is a full offline suite, and Google Workspace's free Docs, Sheets, and Slides dominate collaborative work in US schools and startups.
Compatibility is the deciding factor for many Americans: if you exchange complex spreadsheets with tracked changes and macros, native Microsoft apps remain the safest. For everyday writing, budgets, and presentations, the free options are more than enough. Download only from the official sources below.

Microsoft 365 vs free alternatives
Your decision usually comes down to three paths:
- Microsoft 365 — paid subscription, full desktop apps, deepest compatibility, OneDrive included.
- LibreOffice — free, full-featured, offline, opens and saves Microsoft formats.
- Google Workspace — free for personal use, cloud-first, unbeatable for real-time collaboration.
Many US households mix these: Google Docs for collaboration, LibreOffice for offline work, and Microsoft only when a workplace requires it.
US pricing and licensing
Microsoft 365 Personal and Family plans are billed in USD monthly or yearly, with the Family plan covering multiple users. Microsoft also still sells one-time 'Office Home & Student' licenses for users who dislike subscriptions. Students and educators at many US institutions get Microsoft 365 free through their school — check your .edu email before paying.
LibreOffice and Google's free tier cost nothing.
Compatibility with US business and schools
Because American workplaces, school districts, and government agencies overwhelmingly use Microsoft formats, file compatibility matters. LibreOffice handles most .docx and .xlsx files well, but very complex documents with intricate formatting or macros can shift slightly. If your job depends on pixel-perfect fidelity with Office, use the native Microsoft apps.
For collaborative documents, Google Workspace exports cleanly to Microsoft formats when you need to hand something off.
Cloud storage and US privacy considerations
OneDrive (Microsoft) and Google Drive both store data on US-based and global servers. For most personal and small-business use this is fine. Organizations handling regulated data — healthcare under HIPAA, or student records under FERPA — should confirm they're on a compliant business or education tier with the right agreements in place. Personal users can simply enable two-factor authentication and a strong password.
Avoiding fake Office downloads and cheap keys
Steer clear of websites selling suspiciously cheap 'lifetime Office keys' — many are gray-market or stolen and stop working. Download Microsoft 365 only from microsoft.com or the Microsoft Store, LibreOffice from libreoffice.org, and use Google's suite directly in your browser. Genuine free options mean there's no reason to risk a sketchy key.
