About this tool

JSON Escape / Unescape makes a string safe to drop inside a JSON document — or reverses the process.

The escaping is done with a spec-correct JSON codec, so it matches exactly what a real JSON parser expects. Everything runs locally in your browser via WebAssembly — nothing is uploaded.

FAQ

Will emoji and accented characters be turned into \uXXXX?

No. The JSON spec only requires escaping double quotes, backslashes, and control characters — so é or 😀 pass through as-is, which every JSON parser accepts. Only control characters (below U+0020) become \uXXXX sequences.

When should I tick "Wrap in quotes"?

Tick it when you want a complete, standalone JSON string token ("like this") you can paste directly as a value. Leave it off when you're splicing the text between quotes that already exist in your document. The option only applies in escape mode.

Do I have to remove the surrounding quotes before unescaping?

No — unescape handles both forms. "a\nb" and a\nb decode to the same two-line result, so you can paste a value straight out of a JSON blob without trimming it first.

Why does unescape report "invalid JSON string escaping"?

The input contains a sequence a real JSON parser rejects — for example \q (not a defined escape) or a truncated \u12 unicode escape. Decoding is done with a spec-correct JSON codec, so anything it refuses would also fail in your application.
