Strengths Comparison
.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).
.WEBP Strengths
- Smaller file sizes than JPEG, PNG, and GIF at equivalent visual quality.
- Single format for lossy photos, lossless graphics, transparency, and animation.
- Full alpha channel support with smaller files than PNG.
- Now universally supported in all modern browsers.
- Open-source reference implementation (libwebp) by Google.
Limitations
.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.
.WEBP — Limitations
- Some older software and image editors still don't read WebP natively.
- Max dimensions are 16,383 × 16,383 — lower than JPEG or PNG.
- Print workflows rarely support WebP (no CMYK, limited color management).
- Editing tools are less mature than JPEG/PNG; round-tripping can lose quality.
Frequently Asked Questions
ODS (OpenDocument Spreadsheet) is a spreadsheet format used to store tabular data in rows and columns, typically with multiple sheets per workbook, cell formatting, formulas, and optional charts. It is part of the spreadsheets & data family and is the native format of a specific spreadsheet application.
WebP is a modern image format developed by Google in 2010. It supports both lossy and lossless compression, transparency, and animation, while delivering files 25-35% smaller than JPEG and PNG equivalents.
Excel, Google Sheets, LibreOffice Calc, and Apple Numbers handle most ODS files with high fidelity. For simple one-off viewing, Google Sheets and the Office web apps open ODS in the browser without installing anything. Convert to XLSX or CSV first if your target tool is strict about formats.
WebP files open natively in Chrome, Firefox, Safari, Edge, and most modern image viewers. On Windows, the Photos app supports WebP. On macOS, Preview handles it from macOS Big Sur onward.
Upload the ODS 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).
