Hi,
it's possible to translate ".obj" to ".wrl 1" only with Freecad.
Open ".obj" mesh in Freecad into Mesh workbench, select mesh and save to "#Inventor V2.1 ascii".
Open file "#Inventor V2.1 ascii" with notepad or other and change the header from "#Inventor V2.1 ascii" by "#VRML V1.0 ascii".
Open file .wrl 1 with FreeShip.
Enjoy
