What is a FODS file?

The FODS format is the Flat XML implementation of the OpenDocument Spreadsheet standard (ISO/IEC 26300). Unlike the standard ODS format, which utilizes a ZIP-compressed container holding multiple XML manifests and assets, FODS stores the entire spreadsheet document-including content, styles, and metadata-within a single, uncompressed human-readable XML file. This structure facilitates version control (e.g., Git) and direct XML manipulation via XSLT transformations without the need for decompression.

How to open a FODS file

FODS files are natively supported by the LibreOffice and Apache OpenOffice suites, which utilize the underlying OpenDocument structure. They can also be opened in any text editor or XML parser for code-level inspection. Microsoft Excel requires third-party plugins or ODF converters to correctly interpret the Flat XML schema.

What is an ODS file?

The OpenDocument Spreadsheet (ODS) format is an XML-based file standard for spreadsheets, maintained by the Organization for the Advancement of Structured Information Standards (OASIS). Standardized as ISO/IEC 26300, ODS utilizes a ZIP-compressed container holding separate XML files for content (content.xml), styles, and metadata. It serves as the native file format for the LibreOffice and Apache OpenOffice suites, offering a vendor-neutral alternative to proprietary formats by strictly adhering to the OpenDocument Format (ODF) specifications.

How to open an ODS file

ODS files are natively supported by open-source suites such as LibreOffice Calc and Apache OpenOffice on Linux, Windows, and macOS. Microsoft Excel (versions 2007 SP2 and later) includes built-in support for opening and saving ODS files, though some formatting variations may occur due to ODF version differences. Google Sheets also provides cloud-based support for importing and editing this format.
