This technology was originally developed by Google. PWA (Progressive Web Apps) makes this possible. In the latest version of Edge, Edge Chromium, you will find the online Microsoft Office suite works the same as the desktop version. Together with OneDrive, Microsoft's online storage solution, this light Office version lets users access the full Microsoft Office software via a browser. Microsoft has offered a free online version of its Office suite for several years, similar to Google's G Suite. Luckily there are some work arounds to save money. However, the Office suite is not free and if you don't have it installed on your workplace PC, you'll have to pay a steep price for license to use at home. It's the most popular office system suite for professional and home use. Microsoft Office includes the programs Word, Excel, PowerPoint, and others.
