Numbers (Apple Numbers Spreadsheet)
Numbers is Apple's spreadsheet format, native to the Numbers app on macOS and iOS. It features a flexible canvas where multiple tables, charts, and images coexist on a single sheet, rather than the rigid grid layout of traditional spreadsheets.

History
Apple released Numbers in 2007 as part of iWork '08. The format was redesigned in 2013 for iCloud compatibility, adopting the same IWA (Protocol Buffer) internal structure as Pages and Keynote.
