Why Convert XLSX to ODS?
While XLSX is widely used, converting to ODS (OpenDocument Spreadsheet) format provides several benefits, especially if you work in environments that prioritize open standards and open-source software. ODS is fully supported by LibreOffice, OpenOffice, and other free office suites, making it an ideal format for users who prefer not to use proprietary software.
Benefits of Converting XLSX to ODS
- Open-source compatibility - Works perfectly with LibreOffice, OpenOffice, and other free office suites.
- Open standards - ODS is an internationally recognized open standard format.
- No lock-in - Avoid vendor lock-in to specific software ecosystems.
- Long-term accessibility - Open formats tend to remain accessible even as software evolves.
- Cross-platform use - Particularly well-supported on Linux and open-source operating systems.

About XLSX and ODS Format Differences
| Feature | XLSX | ODS |
|---|---|---|
| Format Type | Microsoft Office Open XML | OpenDocument Spreadsheet |
| Primary Software | Microsoft Excel | LibreOffice/OpenOffice Calc |
| Standard Type | ISO/IEC standard (proprietary origins) | OASIS Open standard |
| File Structure | ZIP with XML components | ZIP with XML components |
| Formula Compatibility | Excel-specific formulas | OpenFormula standard |
While both formats are technically XML-based and compressed in ZIP containers, there are important differences in how they handle formulas and certain advanced features. Our converter ensures that basic spreadsheet functionality is preserved during conversion, including most common formulas, formatting, and multiple sheets.
However, very complex Excel-specific functions or features might not convert perfectly to ODS format. For most business and personal spreadsheets, the conversion will maintain all essential functionality and appearance. If your spreadsheet uses advanced Excel-only features, you may need to make minor adjustments after conversion.

Frequently Asked Questions
Will all my Excel formulas work in the converted ODS file?
Most common Excel formulas will convert properly to ODS format, as LibreOffice and OpenOffice support many of the same basic functions. However, some Excel-specific or advanced formulas might not have direct equivalents in the OpenFormula standard used by ODS. In these cases, the formula might need adjustment after conversion. For basic arithmetic, statistical, logical, and lookup functions, you can expect good compatibility between the formats.
Will macros in my XLSX file be preserved when converting to ODS?
No, macros from Excel (VBA code) will not convert to ODS format, as they use completely different programming languages and frameworks. ODS files typically use Basic, Python, or JavaScript for macros instead of VBA. If your workflow depends on Excel macros, you'll need to recreate similar functionality using LibreOffice/OpenOffice macro languages after conversion.
Can I open ODS files in Microsoft Excel?
Yes, modern versions of Microsoft Excel (2010 and newer) can open ODS files, though with some limitations. Excel's support for ODS has improved over the years, but you might still encounter issues with certain formatting, formulas, or features. For the best compatibility when working with ODS files, using LibreOffice or OpenOffice is recommended. If you need to frequently switch between Excel and open-source office suites, it's worth testing your specific use case to identify any potential compatibility issues.
