How It Works
How to Convert XLS to ODS
Click inside the file drop area to upload your XLS file or drag & drop it.
Locate your XLS file on your device—typically used for various purposes. Ensure the file is under 50MB to avoid upload issues. If the upload fails, check your internet connection or try compressing the file first.
Select ODS as the output format and click the 'Convert' button.
Choose ODS based on your needs—different formats suit different purposes, like JPEG for smaller file sizes. The conversion process typically takes a few seconds, depending on file size and server load.
Download the converted ODS file instantly after conversion.
Once the conversion is complete, click the download link to save your ODS file. You can then open it in software like a compatible viewer. If the file doesn’t download, ensure your browser allows pop-ups from RunConvert.
You can also send a link to the converted file via email. (Optional)
Enter an email address to receive a secure link to your converted file, which is useful for sharing with clients or accessing later. Links expire after 24 hours for security, and RunConvert ensures your data is protected during transmission.
