Can you create a script/add-on to quickly rescale models in FBX file?

I am looking for a quick and easy way to rescale FBX files.

I am NOT familiar with 3d modeling or how to use tools like Blender.

Is there any type of script or add-on or a way to make a simple drag and drop application that can import an fbx file, rescale it, and then export new fbx file?
