Paste a JSON-as-a-string value - the kind you get when an API response, a log line, or LLM output wraps real JSON inside a quoted string with escaped quotes and \n newlines - and Jsontify automatically detects it and shows an Unstringify button in the raw pane toolbar.
Click it and the escaped string is un-escaped and parsed, replacing your document with the real, readable JSON underneath - properly indented objects and arrays instead of a single line full of backslashes. It's a single undoable edit, so Cmd+Z (or Ctrl+Z) restores the original escaped string exactly.
This is the reverse of Stringify (see the JSON Escape tool) and the most common case where it's needed: a field in an API response that is itself a JSON string rather than a nested object, or a chat or log export where JSON got escaped once for storage and now needs to be read as JSON again.
Detection and un-escaping both run in the same background worker as parsing, so even a large escaped blob unstringifies instantly, and the result is immediately explorable in the tree and inspector - nothing is uploaded to our servers in the process.
