What Is a .ods File?

ODS is the spreadsheet format defined by the OpenDocument Format standard (ISO/IEC 26300). It stores spreadsheet data as XML within a ZIP archive, supporting multiple worksheets, formulas, charts, pivot tables, conditional formatting, and data validation. ODS is the default format for LibreOffice Calc and Apache OpenOffice Calc. The format was designed to be an open alternative to proprietary spreadsheet formats, ensuring that spreadsheet data remains accessible across different software implementations over time. ODS supports a comprehensive formula language that is mostly compatible with Excel functions, though some advanced features may differ in behavior. The format includes support for named ranges, database ranges, scenarios, and external data links. Many organizations choose ODS for its open specification and guaranteed long-term accessibility, particularly in government and academic settings where document preservation is critical.
