What is a JSON stringify example?

A JSON stringify example demonstrates converting JavaScript objects to JSON strings. Basic example: JSON.stringify({name: "John", age: 30}) returns '{"name":"John","age":30}'. With arrays: JSON.stringify(["apple", "banana"]) returns '["apple","banana"]'. For nested objects: JSON.stringify({user: {name: "John", address: {city: "NYC"}}}) produces nested JSON. The method accepts parameters for formatting: JSON.stringify(obj, null, 2) adds 2-space indentation for readability. You can also filter properties: JSON.stringify(obj, ["name", "age"]) includes only specified keys. Use our JSON Formatter at jsonconsole.com/json-formatter to view and beautify stringify output, making it easier to verify and debug. The formatter shows exactly how your JavaScript objects will look when serialized, helping you understand the stringify process and catch any issues before sending data to APIs or storing in files.
