XLS to ODTConverter — Fast & Free Online
Convert XLS to ODT — original file stays on your device, only the upload goes to the server. XLS (XLS (Excel 97-2003)) is microsoft excel's legacy binary spreadsheet format.
How XLS to ODT Conversion Works
XLS is a spreadsheet format: it stores data in the XLS format. ODT is a document format that stores text and formatting as a zipped ODF XML archive, the ISO-standardised open alternative to DOCX. This converts the tabular data into a fixed-layout document suitable for printing or sharing. Metadata such as creation date and embedded colour profiles is preserved where the target format supports it. Converting between these two formats is common when the source application does not support ODT natively or when the target platform only accepts ODT. 1converter processes this conversion server-side using open-source tools. Files are transferred over HTTPS, converted on secure cloud servers, and automatically deleted after 24 hours.
