Converting a series of nested JSON files to single CSV

Let me first say that I am quite new to Python. I need help with converting a bunch of Nested JSONs to a single CSV file. I have looked in to some functions that would do that but I am really new at Python and am getting stuck with even the basics such as syntax for reading files. Thanks!

I tried flattening data function but not sure how to use it correctly.

    Here’s a simplified approach:

    Step 1: Read the JSON File
    First, you need to read your JSON file. Assuming your JSON file is named data.json, you can use the following code:

    import json

# Load JSON data
with open('data.json', 'r') as file:
    data = json.load(file)

    Step 2: Flatten the Nested JSON
    Flattening a nested JSON means converting it into a format where each nested element becomes a new column in your CSV. Python doesn’t have a built-in function for this, but you can use the pandas library which simplifies the process.

    import pandas as pd
from pandas.io.json import json_normalize

## Flatten the data
flat_data = json_normalize(data)

    Step 3: Export to CSV
    Once you have a flattened DataFrame, you can easily export it to a CSV file.

    flat_data.to_csv('output.csv', index=False)
