JSON Stringify & Escape

Stringify and escape JSON strings

Escaping (or "stringifying") turns a piece of text into a single JSON string: it wraps the text in double quotes and replaces the characters JSON can't contain raw — double quotes become \", newlines become \n, tabs become \t — so the whole thing becomes one safe, valid string value.

You need this whenever JSON has to live inside something else: embedding a JSON payload as a string field in another JSON document, pasting it into a code literal, storing it in an environment variable, or putting it on a single line in a log.

Unescaping back to raw text

The reverse is just as common. When you find a JSON value that was stored as an escaped string — a stringified payload in a log line, a serialized field in a database, an API response wrapped in quotes — unescape mode decodes every escape sequence back to the original, readable text. Paste the escaped string with or without its surrounding quotes and the tool figures out the rest.

Escape JSON for code, configs, and logs online

Whenever JSON has to live inside another string — an environment variable, a single-line log entry, a code literal, or a field in another JSON document — it has to be escaped first. Escape JSON online here and get back a single safe string with quotes, newlines, and tabs encoded correctly; switch to unescape mode to turn a stored, stringified value back into readable JSON.

What is stringified JSON?

Stringified JSON is a JSON object or array that has been serialized to a plain string — the result of calling JSON.stringify() in JavaScript, json.dumps() in Python, or an equivalent serialization method. The output is a valid JSON string that contains an entire JSON document, with inner double quotes backslash-escaped and newlines encoded, so the whole document fits safely inside a single string value.

Stringified JSON appears constantly in logs, database columns, environment variables, and API response fields — anywhere structured JSON is stored as flat text. This tool both stringifies (escapes JSON into a safe string) and unstringifies (unescapes a stored string back to readable JSON). The two directions are the exact inverses of JSON.stringify and JSON.parse. For which characters get escaped and why, see how escaping and unescaping JSON strings works.
