What is a JSON viewer?

A JSON viewer is a tool that displays JSON as a tree instead of plain text. Every object and array is a branch under its key. Since it is used to read JSON, a JSON viewer is also called a JSON reader.

How to view JSON online?

Paste JSON into the editor and press View to see it as a tree. If your JSON is invalid, the editor marks the line with the error. Press Fix to repair common mistakes; the JSON Fixer page lists what it corrects.

How to view a JSON file online?

Press Upload, pick a .json file on your computer, and press View to read it as a tree. A .json file is plain text, so any text editor opens it too, but without the tree.

JSON Viewer Example

Below is a JSON API response as plain text and the same JSON as a tree in the viewer.

JSON Response
{"page": 2, "total": 14, "users": [{"id": 7, "email": "[email protected]", "active": true}, {"id": 8, "email": "[email protected]", "active": false}]}

JSON Viewer Tree
▾ object {3}
      page : 2
      total : 14
    ▾ users [2]
        ▾ 0 {3}
              id : 7
              email : [email protected]
              active : true
        ▸ 1 {3}

Do I need to install a desktop app or plugin to view JSON?

No. This JSON viewer runs in your web browser, so there is no browser extension or desktop app to install. Your JSON is sent to ReqBin only when you press Save or Share.
