Program written on Python language. Converting not universal now, it was targeted on Blender OBJ files. As I saw, 3d Max for example have different positions in OBJ files, even names same... It possible to edit positions, program read. I can do it for you, just right for your example.
I was searching myself for such thing, but not found nothing just garbage, which not work. This program working, I used this myself, so can give warranty.
It very simple to use, have README file in package. You can use this in more broad ways you can find.
This program very simplify your life. Please enjoy.
