Microsoft offers several ways to access Word and Excel without spending a penny, but they’re not all equal. Between the web version available in a browser, mobile apps subject to screen-size requirements, and student licenses that vary by institution, “free” can mean very different things. Understanding these distinctions before you get started can help you avoid discovering limitations later on.
Microsoft 365 web version: what you can and can’t do in a browser
The most straightforward way to use Word and Excel for free is through Microsoft 365 for the web, which is accessible from any browser. Simply create a free Microsoft account on the official website, then go to office.com to open Word, Excel, or PowerPoint directly in your browser window.
This version lets you create, edit, and share documents with other users in real time. Files are stored on OneDrive, which comes with a limited amount of storage to start with. For everyday tasks (writing letters, creating simple spreadsheets, and making presentations), the web version covers most needs.
Before looking for ways to install Word and Excel for free on a computer, it’s worth knowing that the web version doesn’t support some advanced features. Excel VBA macros and Word mail merge are not available in the online interface. Anyone who relies on these tools for their day-to-day work will hit a wall.
The other limitation is the need for a constant internet connection. The web apps don’t have an offline mode. On a Chromebook, this limitation is permanent, since Microsoft 365 desktop apps can’t be installed on it at all.
Microsoft 365 student license: a school email address isn’t always enough
Microsoft offers students and teachers free access to Microsoft 365, often presented as the ideal solution. The reality is more nuanced than promotional pages suggest.
Eligibility depends on the institution, not just the school email address. For students to access the apps, their school or university must have signed up for the Microsoft Education program and activated the relevant licenses. An address ending in .edu or .ac.fr doesn’t guarantee access on its own.
The license assigned then determines exactly what the offer includes. There are two possibilities:
- The Office 365 A1 license provides access to the web apps only (Word, Excel, and PowerPoint in a browser), with no option to install them on a computer.
- The more comprehensive A3 or A5 licenses allow users to download and install the desktop apps on a PC or Mac, but not all institutions offer them.
To check your status, sign in to the Microsoft 365 portal with your school account and look for the “Install apps” option on the home page. If it doesn’t appear, your active license only covers the web version. Your institution’s IT department can clarify which license you have and, in some cases, enable access to the desktop apps.
Word and Excel mobile apps: screen size matters
You can download the Word and Excel apps for free on your smartphone from the iOS and Android app stores. On a phone, you can create and edit documents without a subscription.
The situation changes on tablets. Full editing on larger-screen devices may require a Microsoft 365 subscription. This screen-size threshold isn’t always clearly communicated when you download the app. On some large Android tablets or iPads, the app opens in read-only mode until you activate a subscription.
This is worth checking before relying on a tablet as your primary workstation. For example, a student planning to write assignments on an iPad Pro could find themselves unable to edit documents without a subscription.
Mobile alternatives to consider
The Microsoft 365 app (formerly Office) combines Word, Excel, and PowerPoint in a single interface on smartphones. It also includes extra features such as document scanning and converting images into Excel spreadsheets. On a small screen, this all-in-one app remains completely free for editing.
Practical steps to access Word and Excel based on your situation
The process varies depending on your user profile and the device you have. Here are the options that actually work without a subscription:
- On a computer (PC, Mac, Chromebook): create a free Microsoft account, go to office.com, and use Word or Excel directly in your browser. No installation required and no software to download.
- As a student or teacher: first check on the Microsoft Education portal whether your institution participates in the program, then see whether your license allows you to install the desktop apps or limits you to the web version.
- On a smartphone: download the Microsoft 365 app from your app store, create or sign in to a Microsoft account, and start editing documents.
- On a tablet: download the app, but test editing before committing to a workflow, because whether editing is free depends on the screen size.
In every case, a Microsoft account is your single point of access. None of the free options are available without one. Creating an account takes just a few minutes and requires only an existing email address.
The choice between the web version and installed apps comes down to how you plan to use them. For everyday office tasks, the browser version gets the job done. For advanced needs (macros, offline work, or managing large files), only locally installed apps will do—and they’re free only with certain student licenses. Knowing where the line is before you get started can help you avoid unpleasant surprises when you need the apps most.
