Excel 2010/2013

Microsoft Excel is a spreadsheet program that originally competed with the dominant Lotus 1-2-3, and eventually outsold it. It is available for the Windows and OS X platforms. Microsoft released the first version of Excel for the Mac OS in 1985, and the first Windows version (numbered 2.05 to line up with the Mac and bundled with a standalone Windows run-time environment) in November 1987. It provided more functionality than the previous version.
