How do I convert a JSON file to a CSV file in python?

Question

I apologize for the large JSON file. I want to be able to create a csv file that extracts each link (under embedLink), the tags, and the rank. However, each of my attempts have come up short. This is the code that I currently have; however, it outputs multiple errors.

json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes: line 1 column 2 (char 1)

import json, csv

Example desired output:

I'm not sure what I'm missing, I've been working on this for a long time and it's been stumping me. If you have any possible solution to my problem, let me know. I'm open to all ideas.

You may use pandas and convert .json first in Dataframe and later in .csv

import pandas as pd
df = pd.read_json('filename.json')
df.to_csv(filename.csv)
