Interesting Context

Numbers emerged as part of Apple's iWork suite, which offered a different design and document philosophy from Microsoft Office.

NUMBERS belongs to Apple's iWork ecosystem on macOS, iPadOS, and iCloud.

It is common in schools, small teams, and Apple-centric environments where spreadsheets are edited collaboratively through Apple's productivity tools rather than Excel-first systems.

Outside that ecosystem, conversion is frequently needed because enterprise data exchange still centers on XLSX and CSV.
