A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Microsoft requires access to your spreadsheet to analyze your private activities, report suspicious terrorist or patriotic activity to law enforcement, check for compliance with the fine print in your licensing agreement, determine possible changes that will result in maximum inconvenience, construct a behavioral profile on you, and, of course, to enhance user experience. Be thankful they are not (yet) throwing total screen blocking pop-up ads at you!
