XLS is Microsoft's proprietary binary spreadsheet format. Converting XLS to ODS produces an open-standard file compatible with LibreOffice, Google Sheets, and all other ODF-compliant applications, freeing your data from Microsoft format lock-in.
Our XLS to ODS converter uses LibreOffice's MS Excel 97 import filter to read the binary .xls file, then exports it in OpenDocument Spreadsheet format. All worksheets, formulas, and cell styles are carried across into the ODS container.
ODS is the ISO 26300 open format for spreadsheets and the default save format for LibreOffice Calc. It is widely used in government, education, and organisations that prioritise open standards and long-term document portability.
Most Excel formulas are fully supported in LibreOffice Calc and will work correctly after converting from XLS to ODS. Excel-specific features such as pivot table definitions and VBA macros do not convert, but tabular data and standard functions are preserved.
