Lesson Notes
Read through the key concepts before you try the challenge.
The browser version is a different tool, not a smaller one
You are covering reception at Lakeside Medical Associates.
You need to fix a typo in a handout while working at a shared workstation that does not have Office installed. Word Online opens the file in a browser and the fix takes forty seconds. Later you try to run a mail merge in the same browser tab and find the command does not exist.
Your task: Know what the browser version does well and where you need the desktop app.
Word Online runs in any modern browser with no installation, which makes it genuinely useful on a shared or borrowed machine. It handles typing, basic formatting, comments, and real-time co-authoring well, and it saves continuously to OneDrive.
| Task | Word Online | Desktop |
|---|---|---|
| Quick edit on a borrowed machine | Yes | Requires installation |
| Real-time co-authoring | Yes | Yes, for files in OneDrive or SharePoint |
| Mail merge | No | Yes |
| Advanced layout: sections, columns, precise object placement | Limited | Yes |
| Macros and add-ins | No | Yes |
| Working offline | No | Yes |
What Is Word Online?
Word Online (also called Word for the web) is a free browser-based version of Microsoft Word available through Microsoft 365. It lets you create, view, and edit Word documents from any device with a browser — no software installation needed.
Accessing Word Online
Go to office.com and sign in with your Microsoft account. Click the Word icon to open Word Online. You can also open any .docx file stored in OneDrive directly in your browser.
Creating a New Document
Click New blank document on the Word Online start page to open a new, blank document. Files are saved automatically to OneDrive as you work.
Editing Mode vs. Reading View
Word Online opens documents in Editing view by default. Click View → Reading View to switch to a clean, non-editable layout. Switch back to Editing view to make changes.
Opening in the Desktop App
If you need features not available in Word Online, click Edit in Desktop App (or Open in Desktop App) in the toolbar. This opens the file directly in the Word desktop application and syncs changes back to OneDrive automatically.
Key Differences from the Desktop App
Word Online covers the most common tasks but lacks some advanced desktop features, including macros, certain advanced layout tools, and some reference and mail merge functions. For basic writing and editing, Word Online works seamlessly.
