Hello Manish,

I appreciate the feedback. As far as we are aware, this exception occurs only with XLS files, which is why this task is specifically logged for the XLS format. However, if during investigation or development it is determined that the issue also affects XLSX files, it will also be addressed appropriately.

Thank you for your collaboration.

Regards,

I shall try the workaround. But please ensure this loading should be working with both Xls and Xlsx.


Regards,

Manish.
