The suite currently includes a word processor (Word), a spreadsheet program (Excel), a presentation program (PowerPoint), a notetaking program (OneNote), an email client (Outlook) and a file-hosting service client (OneDrive). The Windows version includes a database management system (Access). Office is produced in several versions targeted towards different end-users and computing environments. The original, and most widely used version, is the desktop version, available for PCs running the Windows and macOS operating systems, and sold at retail or under volume licensing. Microsoft also maintains mobile apps for Android and iOS, as well as Office on the web, a version of the software that runs within a web browser, which are offered freely.
Since Office 2013, Microsoft has promoted Office 365 as the primary means of obtaining Microsoft Office: it allows the use of the software and other services on a subscription business model, and users receive feature updates to the software for the lifetime of the subscription, including new features and cloud computing integration that are not necessarily included in the "on-premises" releases of Office sold under conventional license terms. In 2017, revenue from Office 365 overtook conventional license sales. Microsoft also rebranded most of their standard Office 365 editions as "Microsoft 365" to reflect their inclusion of features and services beyond the core Microsoft Office suite. Although Microsoft announced that it was to phase out the Microsoft Office brand in favor of Microsoft 365 by 2023, with the name continuing only for legacy product offerings,[20][21] later that year it reversed this decision and announced Office 2024, which they released in September 2024.[22][23][24]
Office on the web is a free lightweight web version of Microsoft Office and primarily includes three web applications: Word, Excel and PowerPoint. The offering also includes Outlook.com, OneNote and OneDrive which are accessible through a unified app switcher. Users can install the on-premises version of this service, called Office Online Server, in private clouds in conjunction with SharePoint, Microsoft Exchange Server and Microsoft Lync Server.[31]
Word, Excel, and PowerPoint on the web can all natively open, edit, and save Office Open XML files (docx, xlsx, pptx) as well as OpenDocument files (odt, ods, odp). They can also open the older Office file formats (doc, xls, ppt), but will be converted to the newer Open XML formats if the user wishes to edit them online. Other formats cannot be opened in the browser apps, such as CSV in Excel or HTML in Word, nor can Office files that are encrypted with a password be opened. Files with macros can be opened in the browser apps, but the macros cannot be accessed or executed.[32][33][34] Starting in July 2013, Word can render PDF documents or convert them to Microsoft Word documents, although the formatting of the document may deviate from the original.[35] Since November 2013, the apps have supported real-time co-authoring and autosaving files.[36][37]
Office on the web lacks a number of the advanced features present in the full desktop versions of Office, including lacking the programs Access and Publisher entirely. However, users are able to select the command "Open in Desktop App" that brings up the document in the desktop version of Office on their computer or device to utilize the advanced features there.[38][39]
The Personal edition of Office on the web is available to the general public free of charge with a Microsoft account through the Office.com website, which superseded SkyDrive (now OneDrive) and Office Live Workspace. Enterprise-managed versions are available through Office 365.[41] In February 2013, the ability to view and edit files on SkyDrive without signing in was added.[42] The service can also be installed privately in enterprise environments as a SharePoint app, or through Office Web Apps Server.[31] Microsoft also offers other web apps in t
