String Escaper

Escape or unescape strings for JSON, JavaScript, HTML, and URLs. Handles quotes, backslashes, and special characters.

How String Escaper Works

A String Escaper is a developer utility used to sanitize text for use in code. This tool is essential for backend engineers and security researchers preventing syntax errors in JSON (RFC 8259) payloads, safely embedding strings in HTML attributes, and preparing data for SQL queries.

The "Safety" Engine

Computers get confused if you put a quote inside a quote.

  • Bad: var text = "She said "Hello""; (Syntax Error)
  • Good: var text = "She said \"Hello\""; (Escaped)
    This tool automates that process for massive blocks of text, ensuring Code Integrity. The escaping rules follow the conventions defined in the ECMAScript Language Specification for JavaScript strings and the OWASP XSS Prevention Cheat Sheet for HTML context safety.

Frequently Asked Questions

Escaping turns special characters (like quotes " or newlines \n) into safe "Text Sequences" (like \" or \\n) so they don't break code. Unescaping reverses this.
