I'm trying to import a csv into a non-standard object. I have no trouble mapping custom fields – name, phone, dates, etc. I'm having trouble importing a lookup field.
The lookup field isn't listed in the available fields there. Is there a reason for that? Or do i need to convert it to a master-detail field first?

There should by no fundamental difference between custom Master/Detail and Lookup fields - except that Master/Detail is always required.
In the Screenshot below you find a custom Object TestChild__c to be imported with a custom lookup field TestParent__c. As you see, you can match Lookups either with their Salesforce Id or with their Name.
