Was JSON String Escape / Unescape useful?
O que é 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.
Como usar
-
Pick the direction
Escape raw → JSON or Unescape JSON → raw. Both directions round-trip cleanly for any valid input.
-
Paste the input
For escape, paste any string (control characters allowed). For unescape, paste the JSON-quoted content (without the surrounding quotes).
-
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.
