What is a JSON Formatter?

A JSON Formatter is an online tool that makes JSON data easier to read and understand. It automatically organizes objects, arrays and values using indentation and line breaks.

JSON, short for JavaScript Object Notation, is one of the most common formats used for exchanging data between applications, APIs and services.

If you receive a large or compressed JSON response, formatting it can make it much easier to identify properties, nested objects and data structures.

How to format JSON

1. Paste your JSON into the input box.
2. Click Format JSON.
3. The formatted JSON will appear in the output box.
4. Use Copy Result to copy the formatted data.

JSON Formatter vs JSON Validator

Formatting and validation are related but different tasks.

A formatter organizes valid JSON to make it easier to read. A validator checks whether the provided data follows the JSON syntax rules.

If your JSON contains a syntax error, the validation function will report the problem instead of returning formatted data.

Example JSON

{

"name": "IceNex",
"type": "Technology",
"tools": [
"JSON Formatter",
"Base64 Encoder",
"UUID Generator"
],
"active": true
}

Is this JSON Formatter free?

Yes. The IceNex JSON Formatter is free to use and does not require registration.

The formatting and validation process is performed directly in your browser. Your JSON is not sent to a server by this tool.
