When importing files in Portal 2.0, you may notice that .XLS files are stored as .CSVs during the import process. This is expected behavior; we process XLS files by converting them to .CSVs on our server. XLS files cannot be processed on the client-side in our importer, which is why setting the managed option to false disables a user's ability to import XLS files in Portal 2.0.
