Stringify JSON

Stringify JSON turns any valid JSON into a compact string. Easily copy or export it for use in JavaScript, storage, or transmission.

Paste your input above or import a file below.
No file chosen
Supported file types: .txt, .csv, .tsv, .log, .json, .xml, .md, .ini, .yaml, .yml, .html, .htm, .css
Total characters: 0

How to Use:

Paste your JSON into the input box on the left, or import a file with the “Choose File” button. The tool will try to parse it and then apply JSON.stringify() to produce a compact, quote-escaped output perfect for embedding in code or sending over APIs. You’ll see the result in the right-hand box, along with a live character count. Hit “Copy Output” to copy it or “Export to File” to download it.

What Stringify JSON can do:

Stringify JSON helps you flatten structured JSON into a safe, encoded string. That’s useful when you need to pass JSON as a string inside JavaScript, store it in a flat database field, or send it as a value in a URL or API body. If your input isn’t valid JSON, it’ll show you the exact issue. If it’s valid, you get a clean, encoded version right away. No setup, no libraries just straight-up stringifying in the browser.

Example:

Input:

{ "name": "Alice", "age": 30, "active": true }

Output:

{"name":"Alice","age":30,"active":true}

(You can safely paste this into code or serialize it as a string value.)

Common Use Cases:

Stringify JSON is perfect when you need to prep data for JavaScript constants, database storage, API transmission, or logging. It’s a handy bridge between readable structure and safe encoding. Whether you’re sending JSON in a query string, injecting it into HTML, or just debugging, this tool gets it done fast.

Useful Tools & Suggestions:

Before converting to a safe string, Escape JSON should be applied so all characters are handled properly. Then, once it’s stringified, JSON Unstringify Text can be used later to bring it back into a workable format if needed.
