Numbers
Apple Numbers Spreadsheet
Numbers is Apple's spreadsheet application, part of the iWork suite, and .numbers is its native file format. Introduced in 2007, the format stores workbooks as a ZIP archive of binary property lists, distinguishing it from the XML-based approach of XLSX. Numbers supports multiple tables per sheet, flexible canvas layouts, and tight integration with Apple's design tools, but documents must be exported to XLSX or CSV for use outside Apple platforms.
