Yes, It will require LLM to convert your unstructured data into a type-safe JSON format, It will be a very simple hobby project that will get you a JSON response as fast as possible instead of writing your own implementation or similar stuff. I plan to simplify this friction because JSON is used in various places. If it somehow works, then I think it would save some time for devs to focus on other parts of their projects :)
Let me know what you think ^_^
