What is an SDC file?
SDC is the legacy spreadsheet format used by StarOffice Calc and early OpenOffice.org releases, the predecessor suites to LibreOffice Calc. It stores cell data, formulas, and formatting using StarOffice's original binary document model, which was superseded by the OpenDocument Spreadsheet (ODS) standard. SDC files typically surface today only when working with archived StarOffice-era spreadsheets.
How to open an SDC file
LibreOffice Calc opens SDC files natively through its built-in legacy StarOffice format support, converting the spreadsheet into its modern editing environment automatically. Apache OpenOffice Calc also supports this older format.

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.
