JSON Stringify/Unstringify
Convert JavaScript objects to JSON strings or parse JSON strings back to readable objects. Pretty-print with customizable indentation.
About This Free Online JSON Stringify/Unstringify
Our free JSON stringify and unstringify tool converts text into a JSON-escaped string and back again, handling the quotes, backslashes, and newline escapes that JSON requires. Stringifying turns raw text into a safely escaped string you can drop into a JSON file or API payload, while unstringifying turns an escaped JSON string back into readable text. Paste your input, choose a direction, and the result appears instantly. Developers use it constantly when embedding text in JSON, debugging API requests and responses, copying log values, and preparing config data. Escaping and unescaping by hand is tedious and easy to get wrong, especially with nested quotes. Everything runs locally in your browser, so it is immediate, free, requires no signup, and keeps your data private.

Frequently Asked Questions About JSON Stringify/Unstringify
What is JSON stringify?
JSON.stringify converts a JavaScript object or value to a JSON string. For example, {name: "John"} becomes '{"name":"John"}'. This is useful for storing data or sending it to an API.
What is JSON unstringify (parse)?
JSON.parse converts a JSON string back into a JavaScript object. For example, '{"name":"John"}' becomes {name: "John"}. This is used when receiving data from APIs.
Can I format minified JSON?
Yes. Paste minified JSON and the unstringify mode will parse and re-display it with your chosen indentation, effectively formatting it.
Why Choose the JSON Stringify/Unstringify?
Developers and power users need tools that are exact and private. The JSON Stringify/Unstringify runs its logic locally in your browser, returns results instantly, and never transmits your input — handy when you are working with keys, hashes, or data you would rather not paste into a remote service.
