JSON Escape & Unescape — String Encoder

Which characters must be escaped in JSON?

Everything else, including emoji and accented letters, is allowed as-is in UTF-8 JSON. Tick ASCII only to write non-ASCII characters as \uXXXX for systems that cannot handle UTF-8. The forward slash may optionally be escaped as \/, which some servers do to keep </script> out of inline JSON.

JSON inside JSON

Some APIs and message queues carry a JSON document as a string field — for example an SQS message body or a webhook payload. JSON → string produces that double-encoded form; String → JSON removes one layer of escaping and pretty-prints the inner document, which is the quickest fix for the dreaded "{\"id\":1}" in logs.

In code

JSON.stringify(text)      // escape (JavaScript)
JSON.parse(escaped)       // unescape
json.dumps(text)          # Python
json.loads(escaped)

Need URL or HTML escaping instead? Use the URL encoder or HTML entity encoder.
