String Escape Tool

Escape or unescape strings for JavaScript, JSON, HTML entities, RegEx, URL encoding, and CSS. Warns if input looks already escaped.

Input

Modes explained

JavaScript — escapes quotes, backslashes, newlines, tabs, and control characters for use inside JS strings.
JSON — similar to JS but strictly follows the JSON spec; wraps in JSON.parse for unescaping.
HTML Entities — converts &, <, >, ", and ' to entity references.
RegEx — escapes special regex metacharacters so a string can be used safely in a pattern.
URL — applies encodeURIComponent / decodeURIComponent for query strings and path segments.
CSS String — escapes quotes and newlines for use inside CSS string values.
