This developer text utility escapes and unescapes backslashes and special control characters in string literals. When preparing raw text for inclusion inside JSON payloads, programming language string constants, or regular expressions, unescaped quotes and line breaks cause syntax parsing failures. This two-way interface automates character escaping directly in client memory.

### String Transformation Logic The tool applies standard bidirectional string replacement rules:

- **Escape Mode:** - Backslashes: `\` becomes `\\` - Double quotes: `"" becomes `\"" - Newlines: Line breaks become literal `\n` - Tab characters: Horizontal tabs become literal `\t` - Carriage returns: Carriage returns become literal `\r` - **Unescape Mode:** - Reverses the transformation, converting literal escape sequences (`\n`, `\t`, `\r`, `\"", and `\\`) back into their native raw character equivalents.

### Concrete Escaping Example Suppose a software developer embeds a multi-line message into a JSON string field:

**Raw Input Text:** ```text Path: C:\Program Files\App Note: "Always verify settings." ```

**Escaped Output String:** ```text Path: C:\\Program Files\\App\nNote: \"Always verify settings.\" ```

The output can be safely pasted directly into JSON properties or JavaScript string literals without causing parser termination errors.

### Privacy and Client-Side Execution All regular expression replacements execute locally in your web browser. No source code snippets, configuration paths, or confidential payload strings are ever uploaded to an external server.
