ODS Format Guide & Converter

OpenDocument Spreadsheet is an OpenDocument Spreadsheet workbook (ZIP of XML) used by LibreOffice and compatible suites, introduced by OASIS (2005). ODS is the open alternative to XLSX for tables, formulas, and charts. It travels well through LibreOffice/OpenOffice; convert to XLSX or CSV when collaborators live entirely in Microsoft Excel or Google Sheets.

ODS does not support an alpha channel. Convert to PNG, WebP, AVIF, or SVG when you need transparent backgrounds.

ODS is a still-media or non-animated format in typical use. Use GIF, APNG, video, or animated WebP when you need motion.

Decision pages that cite ODS — the next hop after a vs comparison.

Tools extend the format graph beyond one-off conversion — compression, metadata, and utilities for real workflows.

Uploading sensitive ODS files to a random converter creates a third-party copy you cannot control. Format Convertly keeps processing on-device so photos, contracts, and exports stay private.
