ODS (OpenDocument Spreadsheet) is the ISO-standardized open format for spreadsheet data. XLS is the legacy Binary Interchange File Format (BIFF8) from Microsoft Excel 97-2003. Converting ODS to XLS produces a binary spreadsheet file compatible with Excel 97 through 2003 and with legacy software systems that were built to process the BIFF binary format exclusively.

Legacy enterprise systems built before 2007 were programmed to parse the BIFF8 binary format. These include custom inventory management tools, older versions of SAP reporting modules, manufacturing execution systems, and government IT infrastructure that has not been modernized. When data originates in LibreOffice Calc and must feed into these systems, XLS is the only accepted format.

Some organizations also maintain XLS as their standard for maximum backward compatibility across their entire IT estate. Machines running Windows XP with Office 2003, field laptops with restricted software installations, and air-gapped industrial workstations may only have access to applications that support the legacy XLS format.

The conversion engine uses LibreOffice in headless mode to parse the ODS XML package and serialize it as a BIFF8 binary workbook. Cell values, formulas (translated from ODF syntax to Excel syntax), number formats, cell styles, and basic charts are mapped to their XLS equivalents. Data exceeding XLS limits (65,536 rows, 256 columns) is truncated. ODS features without BIFF8 equivalents are simplified or removed.

Rows beyond the XLS limit of 65,536 per sheet are truncated. Split large datasets across multiple sheets before converting.

Yes. Standard formulas are translated from ODF syntax to Excel's syntax. ODS-specific functions without Excel equivalents may need manual replacement.

Basic chart types convert to their XLS equivalents. Complex or LibreOffice-specific chart features may be simplified during conversion.

XLS files are usually larger than ODS because the BIFF binary format lacks ZIP compression. Expect 30-50% size increase.

LibreOffice Basic macros do not convert to Excel VBA. The XLS output contains data and formatting only. Macros must be rewritten in VBA separately.
