Understanding Apple Numbers & Microsoft Excel Architecture
Why spreadsheet files behave differently across Mac, iOS, and Windows devices.
The OpenXML Grid System
Microsoft Excel workbooks (.xlsx) use the OpenXML compressed archive format. Worksheets consist of a rigid, infinite grid of 1,048,576 rows by 16,384 columns, where every element must exist inside cell coordinates.
The Apple Freeform Canvas
Apple Numbers departs entirely from single-grid spreadsheets. Instead of an infinite grid, Numbers sheets are flexible graphical canvases that host multiple independent tables, charts, and media blocks side-by-side.
FileZenith Local Package Engine
