String to JSON — Parse Escaped JSON Strings Online

What is String to JSON?

Convert escaped JSON strings into readable JSON objects or arrays. Useful for logs, payload debugging, and API testing.

String to JSON parses escaped JSON string content and converts it into formatted JSON. It can unwrap nested string layers when your payload has been encoded multiple times in logs or middleware. All processing is done in your browser for privacy.

How to Use String to JSON

  1. Paste or type your input into the editor on the left panel.
  2. Results update automatically while you type. You can also press Ctrl+Enter to force a refresh.
  3. View the result in the output panel on the right with full syntax highlighting.
  4. Use Copy or Download to export the result.
  5. Drag and drop .json or .txt files directly into the editor.
  6. Toggle Tree View for an interactive, collapsible view of the JSON structure.

Example

Input:

"{\"user\":{\"id\":101,\"name\":\"Ava\"},\"active\":true}"

Output:

{
  "user": {
    "id": 101,
    "name": "Ava"
  },
  "active": true
}
