How do I convert an XLS file to ODS using LetsConvert?

Upload your XLS file, choose ODS as the output format, and click Convert. The tool processes each sheet, preserving formulas, cell formatting, and layout. Once done, download the converted ODS file and open it in LibreOffice, OpenOffice, or Google Sheets.

Why should I convert XLS to ODS instead of keeping it in Excel's format?

ODS is an open standard format (ISO/IEC 26300) that works natively in free office suites like LibreOffice and Apache OpenOffice. Converting XLS to ODS ensures your spreadsheet remains accessible without Microsoft Excel, reduces vendor lock-in, and can sometimes result in smaller file sizes due to XML-based compression.

What happens to my formulas, macros, and chart formatting during XLS to ODS conversion?

Formulas are translated into ODS syntax and remain fully functional. Basic macros in VBA are not directly compatible; they are either stripped or converted to LibreOffice Basic equivalents depending on complexity. Chart types, cell styles, conditional formatting, and data validation are mapped to their ODS equivalents, but advanced Excel-specific features like dynamic arrays or proprietary functions may lose fidelity.

Is XLS-TO-ODS free to use?

Yes, XLS-TO-ODS on LetsConvert is 100% free with no registration or hidden fees required.

Are my uploaded files safe and secure?

Does this converter work on mobile phones and tablets?

Yes! XLS-TO-ODS works seamlessly across iPhone, Android, iPad, Mac, Windows, and Linux browsers without installing any app.

Is there any software installation required?

No software or browser extension installation is needed. All conversions are performed directly online.
