String Escape / Unescape

Add or remove escape sequences for 18 contexts: JSON, JavaScript, HTML, XML, URL and form encoding, regex literals, bash single and double quotes, CSV fields, C#, Java, Python and Go string literals, YAML double-quoted scalars, Java .properties, ANSI SQL and MySQL backslash escaping. Auto-detect the direction, escape non-ASCII as \uXXXX, and wrap the result as a quoted literal or heredoc.

Pick a context, paste text, and the escaped form updates live — ⌘Enter swaps output back into the input

Body of a JSON string literal: backslash, quote and control characters become \n, \t, \", \uXXXX. Unescape accepts a bare body or a full "quoted" literal.
