└── README.md

How to Use

  1. Enter text with escape sequences in the left panel
  2. See the unescaped result in the right panel in real-time
  3. Copy the visualized output as needed

Implementation Details

  • Backend uses Hono framework to serve the frontend files
  • Frontend uses vanilla JavaScript for the escape sequence conversion
  • The tool uses JavaScript's JSON.parse() with a string wrapper to handle the conversion of escape sequences to their actual characters
  • This approach handles all standard JSON escape sequences

Examples

Input: Hello\nWorld Output:

Hello
World

Input: Tab:\tIndented Output: Tab: Indented
