The Solution: Normalizing JSON and Structuring Data

To convert the JSON data into a cleaner Pandas DataFrame, you can use the following methods:

Method 1: Using json_normalize

This is a straightforward approach to normalize your JSON response.

What This Code Does:

Fetches the JSON: We first pull the data using the requests library.

Splits Columns: The columns are split based on periods (.) to separate the nested structure.

Reshapes: We reshape the DataFrame to get it in a user-friendly format.

Method 2: Creating DataFrame with Constructor and Pivoting

If you want another approach, consider using a list comprehension along with pivoting:

Explanation of This Method:

This method constructs a DataFrame from the JSON data by iterating over nested dictionaries and then using the pivot function to reshape the data.

Conclusion

By following these methods, you can effectively normalize JSON data into a structured Pandas DataFrame. This allows for more efficient data manipulation and analysis. With these techniques, you can transform complex JSON structures into user-friendly formats, enabling you to derive insights quickly.

Feel free to experiment with these methods on your JSON data to find the one that best fits your needs! Happy coding!
