Formatted JSON
What is JSON?
JSON stands for JavaScript Object Notation. It is an open and lightweight format that uses human-readable text to structure, store, and transmit data over the network. JSON is a very common data format that is often used to store and transfer data objects, for example, from server to client or from API client to API server. JSON is a self-descriptive and easy to understand format. The MIME type for JSON is: application/json. JSON file names use the .json filename extension.
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.
