Sorry for this incorrect output. Earlier my code wasn't compatible with deep nested Json.
Thanks for pointing that out and now I have successfully modified codebase to support the similar JSONs.
You can try it out!!
Please feel free to report any more obstacle in app experience.
Sorry for the inconvenience.
The problem was that my logic was working for few working types and sets of json.
So, it wasn't able to recognize your need. So now I have made the logic more robust, so it can handle wide range of json types.
