JSON Formatter & Validator

What is a JSON formatter?

A JSON formatter takes compact or difficult-to-read JSON and reorganises it with indentation and line breaks, making the data easier to read and understand.

JSON, or JavaScript Object Notation, is a lightweight data format commonly used for APIs, configuration files and transferring data between applications.

How to format JSON

1. Paste your JSON into the input box.
2. Choose your preferred indentation.
3. Click Format.
4. Copy or download the formatted JSON.

How to validate JSON

JSON must follow a specific syntax. Common problems include missing commas, incorrectly placed quotation marks, unmatched brackets and invalid values.

Paste your JSON into the editor and click Validateto check whether it is valid JSON.

How to minify JSON

Minifying JSON removes unnecessary whitespace, line breaks and indentation while keeping the underlying data unchanged.

Minified JSON is useful when you want a smaller representation of your data, particularly when transferring JSON between applications or APIs.

Example JSON

{
  "name": "Tiny Utils",
  "type": "utility",
  "features": [
    "calculators",
    "developer tools",
    "converters"
  ],
  "active": true
}
