String Escape Unescape

Escape or unescape strings for JSON, HTML, URL components, and Unicode sequences. This helps when preparing API values, embedding text in code, reading encoded logs, or debugging copied data.

Available escape formats

• JSON escapes quotes, backslashes, line breaks, tabs, and control characters for a JSON string.
• HTML converts characters such as <, >, and & to or from entities.
• URL uses percent encoding suitable for a query value or other URL component.
• Unicode converts characters to \uXXXX or code-point escape sequences and back.

How to use the result safely

Choose the format expected by the destination system, because the same text is escaped differently in JSON, HTML, and URLs. Escaping changes representation; it does not encrypt, sanitize every security context, or validate a complete document. For a full URL, encode individual parameter values instead of encoding the entire address.
