What is JSON?
Why format and validate JSON?
JSON is primarily used to transfer data over a network, and many servers minify it to save bandwidth. This does not affect the data in the JSON file, but it makes the JSON code unreadable to humans. Also, sometimes, when generating a JSON file, servers may incorrectly form JSON, which can lead to damage to the transmitted data and incorrect operation of the API. Therefore, for debugging purposes, you often need to beautify the JSON and check for errors.
