Formats
JSON and JavaScript escape quotes, backslashes and control characters (JS also escapes single quotes). HTML uses entities for the reserved characters. SQL doubles single quotes (' → '') for use inside a quoted literal.
Unescape
Tick Unescape to reverse: JSON/JS unescape sequences like \\n and \\", HTML decodes entities, and SQL collapses '' back to '.
