What is JSON Unescape?

JSON Unescape is the process of converting a string that contains escaped characters back into its original, standard JSON format. In many systems, when a JSON object is stored or transmitted as a string within another structure (like another JSON object, a database field, or a log file), its special characters are "escaped." This means a backslash (\) is added before characters like double quotes ("), backslashes (\), and newlines.

Unescaping reverses this process, removing the extra backslashes to make the JSON object readable and parsable again.

Why Do We Need to Unescape a JSON String?

You often encounter escaped JSON strings in various programming and data-handling scenarios:

• API Responses: Some APIs embed a JSON object as a string within a larger JSON payload.
• Databases: Storing a JSON object in a string-based column in a database often requires escaping it.
• Log Files: Logging systems frequently serialize complex objects into an escaped string format for easy storage.
• Data Transmission: When sending data between different systems, escaping ensures that the data is not misinterpreted during transit.

Before you can work with this data in your application (e.g., in JavaScript, Python, or Java), you must unescape it to parse it into a native object. Our tool automates this tedious and error-prone task.

2. Click Unescape: Press the large "Unescape JSON" button.
3. Get the Result: The tool will instantly process your string. The clean, correctly formatted, and unescaped JSON will appear in the right-hand output box.
4. Copy or Clear: You can use the "Copy" button to copy the result to your clipboard or the "Clear" button to start over. You can also load a "Sample" to see how it works.

Example of JSON Unescaping

Here’s a practical example of what the tool does.

Input (Escaped String):

"{\"id\":123,\"user\":\"jane.doe\",\"active\":true,\"roles\":[\"admin\",\"editor\"],\"metadata\":{\"last_login\":\"2023-10-27T10:00:00Z\",\"theme\":\"dark\"}}"

Output (Unescaped and Formatted JSON):

{
  "id": 123,
  "user": "jane.doe",
  "active": true,
  "roles": [
    "admin",
    "editor"
  ],
  "metadata": {
    "last_login": "2023-10-27T10:00:00Z",
    "theme": "dark"
  }
}

This tool is built entirely with client-side JavaScript, meaning your data is never sent to a server. It's fast, secure, and completely private.
