How to Format JSON

How to Format JSON

When JSON data is transmitted over a network, it is often "minified" — stripped of all spaces and line breaks to save bandwidth. While efficient for machines, minified JSON is nearly impossible for humans to read.

The Solution: JSON Formatting

Formatting (or beautifying) JSON restores its readability by adding proper indentation, line breaks, and spacing.

Minified JSON Example:

{"user":{"id":1,"name":"Alice","roles":["admin","editor"]}}

Formatted JSON Example:

{
  "user": {
    "id": 1,
    "name": "Alice",
    "roles": [
      "admin",
      "editor"
    ]
  }
}

Using JSON Format Tools

The easiest way to format your JSON is using the JSON Format Tools Formatter.

  1. Paste your raw JSON into the editor.
  2. Select your preferred indentation (2 spaces, 4 spaces, or tabs).
  3. Click Format to instantly beautify your data.

All processing happens locally in your browser, keeping your data completely secure.
