NUMBERS vs TXT — Strengths and limitations
What each format does best, and where it falls short.
NUMBERS Strengths
- Beautiful layout — charts and tables float as design elements.
- Free on every Mac, iPad, iPhone, and iCloud.
- iCloud sync and collaborative editing.
- Apple Pencil handwriting input on iPad.
- Cleaner for simple budgets, trackers, and presentations than Excel.
Limitations
- Apple-only — Windows and Linux cannot open Numbers files natively.
- Opaque IWA binary format — no third-party inspection.
- XLSX round-trips often lose Numbers-specific layout tricks.
TXT Strengths
- Universally readable — every operating system, every editor, every programming language.
- Zero metadata overhead: the file size equals the character count (for ASCII).
- Safe to diff, grep, version-control, and pipe through command-line tools.
- Immune to format obsolescence: a text file from 1970 still opens today.
- Tiny footprint for structured data like logs or configuration.
Limitations
- No styling, images, or embedded structure — just characters.
- Character encoding ambiguity (ISO-8859-1 vs UTF-8 vs Windows-1252) causes "mojibake".
- Line-ending differences between OSes still cause subtle bugs today.
