With so much free office software available from different providers, it’s a little surprising that Microsoft has come so late to the game. We’re glad they did, though: Office on the web (formerly Office Online) is lightweight but surprisingly feature-rich, making it one of the best productivity tools available for free. 

Businesses and individuals looking for simple document, spreadsheet, and slideshow creation and collaboration will find the free, online apps more than sufficient. However, not all Office apps are available, and some important features are missing. For this reason, creators of advanced and professional content will want to opt for Microsoft 365.
