I don't use Microsoft Office very often. I do most of my writing in Obsidian and my number crunching in Google Sheets. Every once in a while, though, someone who does use Office sends me a Word document or an Excel spreadsheet. What do I do if I want to open it, make edits, and send it back? In this situation, it's probably excessive to purchase Microsoft Office. A one-time purchase of the Microsoft Office suite costs $150, which is a lot for the occasional file. An alternative is Microsoft 365, which starts at $100 per year or $10 per month. Unless I subscribe for a month and then cancel (which is an option), that's also too much for light usage. But I don't have to pay or resort to using a third-party editor like the ones from Google or Zoho. There's an entirely free version of Microsoft Office. The catch is that it only runs in the browser. The Free Version of Microsoft Office Microsoft 365 for the web offers free, web-based versions of familiar Office tools.

After signing in you will be redirected to Microsoft 365 with a free account. From here you can access the free, online versions of Word, Excel, PowerPoint, OneDrive, and Outlook. You can also click the Upload button in order to edit any file that you have on your computer. This will upload the file to your OneDrive, allowing you to open it in the web version of the Office program you need.
