Yes but you need a marketplace module for that. Look for the Excel importer module: https://marketplace.mendix.com/link/component/72
With that module you can use templates to import different Excel sheets. My advise would be to first to an import to shaduw entities. Once the data is in you can then process the data to the entities you would like the data to end up. This way you have much more control over the data coming in.
