Strengths Comparison
.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.
.ODS Strengths
- Open standard (ISO/IEC 26300).
- Native to LibreOffice, OpenOffice, Collabora.
- Human-readable XML, easy to script.
- Preferred by governments and open-data initiatives.
- Supports macros via Basic (BeanShell, Python also possible).
Limitations
.NUMBERS — 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.
- Limited advanced statistical functions and no VBA-equivalent macros.
- Niche in corporate use — Excel still dominates business.
.ODS — Limitations
- Excel opens ODS but often loses conditional formatting and advanced formulas.
- Microsoft-specific formulas (FILTER, LAMBDA) rarely round-trip.
- Business adoption is niche — XLSX dominates real-world exchange.
- Complex cross-sheet macros may break between ODS and Excel workflows.

Excel, Google Sheets, LibreOffice Calc, and Apple Numbers handle most NUMBERS files with high fidelity. For simple one-off viewing, Google Sheets and the Office web apps open NUMBERS in the browser without installing anything. Convert to XLSX or CSV first if your target tool is strict about formats.

Upload the NUMBERS to KaijuConverter and pick XLSX, CSV, ODS, TSV, or PDF. Our LibreOffice-based pipeline reads the sheet data, preserves cell types (numbers, dates, strings), and writes a clean target file. Multi-sheet workbooks come back as a single multi-sheet export or a ZIP of per-sheet CSVs depending on target.
When converting between spreadsheet formats that support formulas (XLSX, ODS), formulas transfer with function-name translation. When converting to CSV, formulas resolve to their cached evaluated value (open the source in Excel once to force evaluation if you suspect stale cache).
