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 OTS file?
The OpenDocument Spreadsheet Template (OTS) is a file format defined by the OASIS OpenDocument standard (ISO/IEC 26300) specifically for creating reusable spreadsheet blueprints. Structurally identical to the ODS format, it uses ZIP compression to package XML content and styles. The primary technical distinction lies in the file header flags, which instruct the software to open a new, untitled instance of the spreadsheet rather than modifying the original template file, preserving the source data structure and formulas.
How to open an OTS file
OTS files function seamlessly with ODF-compliant software including LibreOffice Calc and Apache OpenOffice across all major operating systems. While Microsoft Excel can open these files, users may need to manually select the file type in the open dialog. Double-clicking an OTS file typically launches a new workbook based on the template rather than opening the template file itself for editing.
