Microsoft Office is an industry-standard suite of office productivity applications. The suite is available for Windows on desktop computers and tablets. It is also available for Mac OS X, although it is more limited compared to Windows.

The most basic Office suite includes the following programs:

  • Microsoft Word - A word processing application used to create documents for business and personal purposes
  • Microsoft Excel - A spreadsheet application used to organize, manipulate, and visualize data
  • Microsoft PowerPoint - A presentation application used to create slide shows
  • Microsoft OneNote - A notebook application used to create free-form pages of notes

Other editions of Microsoft Office, such as Office 365, offer Outlook, Publisher, and Access. Each program that makes up the Office suite uses the Open XML format, which uses popular file extensions such as .DOCX, .PPTX, and .XLSX. Office applications also supports add-ins, or plugins, that you can download to extend the capabilities of the programs.

Whether it is used for business or personal use, Microsoft Office is the leading office productivity suite. You can purchase Office with a one-time payment or with a subscription. Free suites, such as Apache OpenOffice, can be used as a substitution in some cases, but since Microsoft Office is standardized within the business and educational community, the price of Office is still worth the purchase.
