What Is a JSON String Escape / Unescape?
JSON string escaping is essential when embedding user input, code snippets, or multi-line text into JSON data structures. Improperly escaped strings cause JSON parse errors that break applications. This tool handles both escaping (text → JSON-safe string) and unescaping (escaped string → original text), supporting all special characters, control characters, and Unicode sequences defined in the JSON specification.

Frequently Asked Questions
What characters need escaping in JSON strings?
Double quotes ("), backslashes (\), and control characters (newline, tab, carriage return, etc.) must be escaped. Newlines become \n, tabs become \t, quotes become \", and backslashes become \\.
Why do I need to escape JSON strings?
JSON has strict string syntax rules. Unescaped special characters cause parse errors — a literal newline inside a JSON string is invalid, as is an unescaped quote. Escaping ensures the string is valid JSON.
What is JSON unescape?
JSON unescape is the reverse — it converts escape sequences back to their original characters. \n becomes a real newline, \" becomes a literal quote. This is useful when reading JSON data that has been double-escaped.
How do I handle Unicode in JSON?
JSON supports Unicode escape sequences: \uXXXX where XXXX is the hex code point. For example, \u00E9 represents e. Characters outside the Basic Multilingual Plane use surrogate pairs: \uD83D\uDE00 for the grinning face emoji.
