What is JSON stringify?

JSON stringify converts a complete JSON document into a JSON string value. The result has surrounding double quotes, while quotes, backslashes, line breaks, and control characters inside the document are escaped.

This is useful when JSON must be stored inside another JSON field, copied into a text column, included in a fixture, or represented safely in logs and configuration. It does not extract values or turn JSON into plain text.

How to convert JSON to a string

Paste valid JSON into the input editor, open a local .json or .txt file, or select Example.
Open Settings only when you need to preserve the original whitespace or wrap long lines.
Select Stringify JSON, or press Cmd + Enter on macOS and Ctrl + Enter on Windows or Linux.
Copy the escaped result or download stringified-json.txt.

By default, the tool removes insignificant JSON whitespace before encoding the document. This keeps the resulting string compact. Preserve source whitespace keeps the original indentation and line breaks, which then appear as escaped whitespace such as \n.

JSON stringify example

Input:

{
  "event": "user.created",
  "user": {
    "id": 42,
    "active": true
  }
}

Default output:

"{\"event\":\"user.created\",\"user\":{\"id\":42,\"active\":true}}"

The outer quotes make the result a JSON string value. Each \" represents a quote that belongs to the JSON document inside that string.

JSON stringify vs JSON minify

Minifying JSON only removes insignificant whitespace. A minified object still begins with { and remains an object-shaped JSON document:

{"name":"Ada","active":true}

Stringifying encodes that entire document as a string, adding outer quotes and escapes:

"{\"name\":\"Ada\",\"active\":true}"

Use JSON Minifier when you only need compact JSON. Use this converter when the receiving field or system specifically expects a string value.

Why does stringified JSON contain backslashes?

JSON strings use double quotes as delimiters. Quotes that belong to the document inside the string must therefore be written as \". A source backslash becomes \\, a line break becomes \n, and a Tab becomes \t.

Unicode text and Emoji remain readable by default. The converter only adds escapes required for a valid JSON string; it does not force every non-ASCII character into a \uXXXX sequence.

Common uses for a JSON string

Embed a JSON document inside another JSON property.
Store structured data in a database text column.
Create test fixtures or mock payload values.
Copy JSON into logs or text-based configuration.
Prepare an escaped value for an API field that accepts text.

Use String to JSON to reverse the conversion. Use JSON Validator when you only need to check strict JSON syntax.

JSON to string FAQ

Does stringifying JSON change its values?

The default conversion changes insignificant whitespace but preserves JSON tokens such as large integers, decimal spelling, property order, duplicate properties, and string escapes. Enable Preserve source whitespace when the exact source spacing also matters.

Can I stringify a JSON array or primitive?

Yes. Strict JSON permits objects, arrays, strings, numbers, booleans, and null as root values.

Why does the output have another pair of quotes?

Those quotes identify the complete result as one JSON string value. Without them, the output would only be an escaped fragment rather than a complete JSON value.

Can this tool repair invalid JSON?

No. It reports invalid syntax without guessing how the source should change. Use JSON Repair when you intentionally want common malformed JSON corrected.

How do I restore the original JSON?

Paste the stringified value into String to JSON. It removes the string encoding and formats the decoded JSON.
