I am unable to reproduce any issue when I convert your shared XLS to PDF with the latest release of GroupDocs.Conversion Cloud Docker Container, 22.10. Please test the scenario with the latest release; it will resolve the issue.
Hi tilal, the problem is still being reproduced at my end, after updating the version. Can you please share the output PDF, maybe we are not looking at the same place.
I tested the scenario with the latest version of GroupDocs.Conversion Cloud Docker Container using the following cURL command. Please see the attached sample output for reference.
