How to convert .js file to .obj or .gltf file?

Hi, I have old 3D JS file, which has these metadata : “formatVersion” : 3.1, “generatedBy” : “Blender 2.7 Exporter”, and its png ( = texture) file. I tried to import this old one by the new Blender, but the blender does not support JS format anymore. Is there a way to convert .js file to .obj or .gltf file?

It depends on what is in that javascript file. Javascript is a programming language, it doesn’t offer any 3D model formats - so whatever is in there, is likely some custom code that generates geometries / meshes / materials.

Thank you !! your explain is useful for me.
