Office Online, introduced by Microsoft as a part of its Office 365 suite, is a collection of web-based applications that offer the core functionality of the traditional desktop Office suite. Unlike the desktop version, Office Online is accessible directly through a web browser, allowing users to create, edit, and share documents without the need to install additional software. With its seamless integration with OneDrive and other cloud services, Office Online enables users to access their documents from anywhere, on any device, making it an ideal solution for individuals and businesses seeking to enhance productivity and collaboration.
