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 XLS file?
The XLS format utilizes the Binary Interchange File Format (BIFF) scheme, serving as the default spreadsheet standard for Microsoft Excel from versions 2.0 through 2003. Encapsulated within the Object Linking and Embedding (OLE) Compound File Binary Format (CFBF), XLS files store data in binary streams rather than XML. This proprietary structure supports formulas, Visual Basic for Applications (VBA) macros, and charts but lacks the compression efficiency and corruption resilience of the newer XML-based standards.
How to open an XLS file
Microsoft Excel remains the primary software for full fidelity access to XLS files. On Windows and macOS, the operating system associates these files with the Office suite if installed. Alternatively, open-source solutions like LibreOffice Calc and Gnumeric provide robust reverse-engineered support for reading and editing XLS binaries on Linux and other platforms without requiring Microsoft licenses.
