JSON String Escape / Unescape

Qu’est-ce que JSON String Escape / Unescape ?

JSON strings must escape a small set of characters: the double quote, the backslash, and the control characters (U+0000 to U+001F). Everything else may appear literally.

This tool implements the standard JSON escaping rules from RFC 8259. The "escape" direction converts a raw string into a JSON-safe form (the content you would put between double quotes). The "unescape" direction parses a JSON string literal back to its raw bytes.

Comment l’utiliser

1. 1

   Pick the direction

   Escape raw → JSON or Unescape JSON → raw. Both directions round-trip cleanly for any valid input.

2. 2

   Paste the input

   For escape, paste any string (control characters allowed). For unescape, paste the JSON-quoted content (without the surrounding quotes).

3. 3

   Copy the output

   Use the escaped form inside a JSON config or template. Use the raw form to inspect what a stored string actually contains.
