Text to JSON Formatter (String to JSON)

Text, Strings, and JSON

JSON is always text. What differs is how many layers of escaping sit between you and the structure. A payload logged with JSON.stringify() twice arrives with \" in place of every quote; parsing it once yields a string, and parsing that string yields the object.

The Three Shapes You Will Paste

• Minified JSON — {"a":1,"b":[2,3]}. One parse, then indent.
• Escaped JSON string — "{\"a\":1}". Parsing unwraps the outer string first.
• Plain prose — not JSON at all, and reported as a syntax error rather than guessed at.

How to Convert Text to Formatted JSON

1. Paste the text into the input pane.
2. If it parses, the output pane returns indented JSON with highlighting.
3. If it does not parse, the error line tells you which character broke it — usually an unescaped quote.

Doing It in Code

// JavaScript — unwrap a doubly-encoded payload
const once = JSON.parse(raw);        // still a string
const data = JSON.parse(once);       // now an object
console.log(JSON.stringify(data, null, 2));
