| Description | Files with a .numbers extension are created by Apple's "Numbers" application which forms part of Apple's iWork office suite, a set of applications which run on the Mac OS X and iOS operating systems, and also includes Keynote (for presentations) and Pages (for word processing).
Numbers 1.0 on OS X was first announced on August 7 2007, and the .numbers file contains many of the standard features of a spreadsheet with support for rows, columns, graphs, formulas and charts. The iPad version of Numbers was released in January 2010, and the most recent version of Numbers on OS X is version 3.5 released in November 2014 as part of Apple's iWork '14 update. As with other products in the iWork suite Numbers includes a variety of layouts designed by professional illustrators and also includes support for importing documents from Microsoft's Office suite (in this case Excel spreadsheets). The key advances in Numbers are summarised below:

| Technical Details | A .numbers file is actually a compressed ZIP file comprised of a number of other different files combined that together make up a .numbers file. The most recent version of Numbers saves files with an "Index" directory containing Apple's proprietary IWA file format, a "Metadata" directory with .plist files and one or more jpg files for allowing quick previews. Similar to Microsoft products, the .numbers file type suffers from a lack of compatibility with other leading spreadsheet programs. | ||||||||||||||||||||||||
