Expected double stringify
Running stringify twice produces an over-escaped value.
Fix: Run unstringify first, or check the input isn't already a literal.

What is JSON Stringify
Last reviewed:
JSON (JavaScript Object Notation) is a lightweight, human-readable data format used almost everywhere on the web for APIs, config files, and log output.
JSON Stringify calls JSON.stringify on your input, treating it as a raw string value. Quotes, backslashes, newlines, tabs, and Unicode characters are escaped according to the JSON spec.
It's the fastest way to prepare text for embedding inside another JSON payload — for example, when storing HTML, XML, or Markdown as a JSON string field.
Why use it
- Embed HTML, XML, or Markdown inside a JSON field.
- Prepare payloads for analytics events that expect a string.
- Generate safe JSON literals for API fixtures.
- Round-trip user-provided content into structured storage.
- Avoid manual escaping when copy-pasting text into JSON.
Features
- Wraps input in a JSON-safe string literal
- Escapes quotes, backslashes, newlines
- Uses native JSON.stringify
- Zero-upload JSON Stringify pipeline, nothing touches a server
- Great for embedding HTML/XML in JSON
How to use JSON Stringify
- Paste text. Drop raw text or code into the input.
- Click Run. The tool produces a JSON string literal.
- Copy literal. Paste into your JSON payload or fixture.
Example (before/after)
Raw text
<p>Hello "world"</p> Line two
JSON string literal
"<p>Hello \"world\"</p>\nLine two"
Common errors
Binary data
JSON strings can't hold raw binary bytes.
Fix: Base64-encode binaries first.
FAQ
How is this different from JSON formatting?
Stringify treats the entire input as a single string value. Formatting pretty-prints an already-valid JSON document.
Does it escape all Unicode?
Standard JSON.stringify behaviour — non-ASCII is emitted literally (UTF-8 safe).
Does it preserve newlines?
Yes — they become \n sequences inside the output string.
Is input uploaded?
No — encoding runs entirely in your browser.
Can I chain it with other escapers?
Yes — e.g., JSON stringify + JS escape for deep-nested literals.
