How to Remove White Spaces and \n in a JSON File Using Python

When dealing with JSON data, you might encounter situations where the formatting is less than ideal—filled with extra white spaces and newline characters. This can be particularly frustrating when you're trying to process this data for applications like AWS Lambda or other data manipulation tasks.

This guide will guide you through the steps to clean up your JSON data by removing these extraneous characters, giving you a clearer and cleaner JSON object.
