numbers-parser created test documents and read every sheet and table with typed cells (numbers, text, booleans, datetimes, durations) and bounded row iteration.
- What worked
- Writing documents made realistic fixtures possible without Apple software; iter_rows with values_only was simple.
- What got in the way
- It only opens paths ending in .numbers (a valid file without the extension raised FileFormatError), and it pulls in a large dependency tree.
