Thank you so much for your inputs @alastairp I submitted a part of my proposal here please check and let me know what you think about it.
Also, I have some more doubts listed there I would be grateful if you could clarify them as well.
I hope I am going in the right way and submit a proper and detailed proposal to work on.
For this, I was thinking if we can have a JSON to CSV converter and store the files in the file system. Still, I am not sure how efficient this is, I will research more on this and try to come up with a better solution.
