Apple Numbers Spreadsheet (.numbers)

The Apple NUMBERS spreadsheet format is used by the Numbers application, which is part of the iWork productivity suite developed by Apple Inc. Files with the NUMBERS extension are classified as spreadsheet files and are similar to XLSX files created by Microsoft Excel. The Numbers application allows users to create and edit spreadsheets, organize data, create charts and graphs, and perform calculations.

Numbers provides a variety of tools for formatting data in cells, including options for formatting numbers, currency, percentages, dates, and time. Users can also create custom cell formats to display other types of data. In addition to formatting options, Numbers also provides tools for organizing data and identifying trends, such as filters, grouping data into categories, and creating pivot tables.
