JSON file to CSV or Oracle Table - json

Question

I have to convert a JSON file in a CSV file or even better, extract the JSON file content in to an Oracle table.
I gave a look into the other topics and the only one that I found is related to the conversion in HTML table.
The files are really unstructured, here an example:

Answer 1

All code is available at github.
The code is updated according to the changed did in csv in 2013 since then CSVs now have headers! The key name for the field is now the first row of the CSV.
https://github.com/vinay20045/json-to-csv
OR
You can use api
https://json-csv.com/api to convert.
Just register there get api accessibility privileges and use thier code. That's it
