JSON Beautifier

Breadcrumbs: Home / Learn / JSON Beautifier

A JSON beautifier formats compact JSON into a cleaner layout with indentation and line breaks, which makes it much easier to scan by eye.

Before and after example

Before: {"name":"ACME","active":true,"items":[1,2]}

After:

{
  "name": "ACME",
  "active": true,
  "items": [
    1,
    2
  ]
}

Use a JSON beautifier when you need to make a compact payload readable before a bug fix, a code review, or a compare run.

It is a good fit for API responses, request bodies, test fixtures, and saved examples that need quick visual cleanup.

Open the JSON tool for formatting, validation, minifying, and viewing.
