Gladly :) I tried to test it directly but the converter is internal and I didn't want to mess with the project structure too much by adding InternalsVisibleTo to the project. Should I follow this approach or test it indirectly by using functions like I wrote in the issue?

Just use the query from your issue and verify that it returns the expected result.
