Hi Marco,
Currently, XlsIO doesn’t have support to export worksheet data to DataTable in ASP.NET Core platform. However, a new feature will be available to Export worksheet data to Business objects or collection in our upcoming release 16.1 which is expected to be rolled out in February 2018.
This feature helps to populate the business objects or model collection from an Excel document very easily.
Please refer below documentation to know more about exporting worksheet data to data table.
The documentation on export to business objects will be available online after the release of 16.1.
Regards,
Abirami.
