DescriptionFiles 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:

VersionDateKey features
1.0August 2007First version - basic features.
2.0January 2009Adds features to allow charts in Keynote and Pages to be automatically updated when changed in Numbers files.
2.1July 2011Support added for OS X Lion features such as "full screen", "resume", "auto save" and "versioning".
2.2July 2012Includes features for integration with iCloud, retina display support and dictation features.
2.3December 2012Includes improved compatibility with Excel documents, the ability to hide and unhide rows and columns amd filters.
3.0October 2013Launched with a new UI to match that found in Pages and Keynote, and also includes the ability to create interactive charts.
3.5October 2014New OS X Yosemite inspired design, support for iCloud drive, and an updated Numbers file format.

Technical DetailsA .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.

Technical DetailsAt the top level iWork '09 numbers files are actually a zip file containing:
  1. An index.xml file
  2. A buildVersionHistory file
  3. A "QuickLook" directory with a "Thumbnail.jpg" of the document. The directory may also contain a PDF file named "Preview.pdf" if the user chose to save the original document with additional preview information in Numbers.
The index.xml is the core component of the file, containing the document content and all of the metadata for formatting it.

Similar to Microsoft products, the .numbers file type suffers from a lack of compatibility with other leading spreadsheet programs.
