OBJ to FBX batch convert

Hallo everyone,

i am tying to convert some (about 500) OBJ files into FBX files using blender.
The OBJ files are generated with OSM2World and i want to use the FBX files in Unreal Engine 4.
A direct OBJ to Unreal Engine 4 import is not working.

Is it possible to convert OBJ files into FBX files with Blender ?
Maybe using some Python script.

best regards,
John
