This JSON formatter helps you turn compact or messy JSON into readable structured output.

It also supports the page model you will later reuse for other formatter and validator tools.

Simple object

A compact object becomes readable formatted JSON.

Input

{"name":"ToolHive","priority":1}

Output

{
  "name": "ToolHive",
  "priority": 1
}

Nested array

A compressed JSON array becomes indented with each element on its own line.

Input

[{"a":1},{"a":2}]

Output

[
  {
    "a": 1
  },
  {
    "a": 2
  }
]

What does a JSON formatter do?

It reformats JSON into readable indentation and helps surface structural mistakes during review.

Why pair formatting with validation?

These intents overlap heavily in search, so one canonical tool page can cover both without splitting thin pages.
