Description Microsoft Excel is a commercial spreadsheet application written and distributed by Microsoft for Microsoft Windows and Mac OS X. Pre-2007 versions of Excel use XLS as the primary format for saving files. It features calculation, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications. It has been a very widely applied spreadsheet for these platforms, especially since version 5 in 1993, and it has almost completely replaced Lotus 1-2-3 as the industry standard for spreadsheets. Excel forms part of Microsoft Office. The current versions are 2010 for Microsoft Windows and 2011 for Mac OS X.

It is now no longer based on SGML, it is designed to be backwards compatible with previous older versions of HTML. HTML5 specifies scripting APIs that can be used with both Javascript and the Document Object Model (DOM). There are also a number of new APIs to include: Canvas Element for 2D drawing, Timed Media playback, Document Editing, Drag and Drop, Web Storage amongst others.
