How to export field collection with Drupal 7 views data export plugin?
If you only need the first result you can add a relationship in the view. Search for the name of the field collection. Once you add this relationship you should be able to access the field collection items and add them to your output.

If you want all the values you need to search add the field collection to your view rather than the fields directly. You then have the options of how to display the results but these options are limited.
