There’s a spreadsheet program that comes with the Mac Operational System which is called Apple Numbers. Actually, it’s a part of Apple’s iWork suite. This program crates files with data organized into rows and columns and may as well be provided with some graphs, tables, images and formulas. Rows are usually labeled with numbers while columns are labeled using letters. An Individual sell can be determined by a unique combination of both. 

Texts, shapes and media such as photos, videos and music could be also added. The application allows viewing data in a number of ways, for example, formatted table or chart. In a way, these files are similar to files created by the Excel application of the Microsoft Office suite in Windows OS. Files made within the Numbers application get the suffix or extension .numbers after they are saved.
