What is the difference between parse and Stringify?

JSON.parse() and JSON.stringify() are opposite operations: parse converts JSON strings to JavaScript objects, while stringify converts objects to JSON strings. JSON.parse() takes a JSON-formatted string like '{"name":"John"}' and returns a JavaScript object you can use in code. JSON.stringify() takes a JavaScript object and converts it to a JSON string for storage or transmission. Use parse when receiving JSON from APIs or reading JSON files to work with the data. Use stringify when sending data to APIs or saving objects to storage. They are complementary: stringify serializes for transport, parse deserializes for use. For example: const obj = JSON.parse(jsonString) then later JSON.stringify(obj). Our JSON tools at jsonconsole.com help visualize both processes: the formatter shows stringified output, while the editor helps you work with parsed objects. Understanding these methods is fundamental to working with JSON in JavaScript applications.
