Multi-Context String Escaper

How it works

Each context has its own well-defined escaping rule. HTML uses entities, JavaScript and JSON produce a quoted string literal, SQL wraps the value in single quotes and doubles embedded quotes, URLs use encodeURIComponent, and regex backslash-escapes metacharacters. Unescaping reverses each rule and reports a clear message when the input cannot be decoded. Invalid input never leaves you with a broken state, and all processing happens in this page — there are no network requests.
