  • Escaping quotes and line breaks for test fixtures.
  • Decoding JSON string values copied from logs.
  • Preparing text for config or payload samples.

Common JSON errors related to escaped strings

FAQ

Does the escaped output include quotes?

Yes. The output is a JSON string literal, including the surrounding quotes.

Can I unescape any random text?

The unescape action expects a valid quoted JSON string. Use escape for raw text.

Why do line breaks become \n?

That is the JSON-safe representation of a newline inside a string literal.

Does this tool upload text or payloads?

No. It runs locally in your browser, so your text is not uploaded.
