What Is a JSON Formatter?

A JSON Formatter is an online tool that makes JSON easier to read by adding proper spacing, indentation, line breaks, and structure. It can also validate JSON and tell you whether your data is correct.

JSON is commonly used in APIs, JavaScript, WordPress, databases, settings files, web apps, mobile apps, and data exchange between systems.

JSON Example

{"name":"John","active":true}

Keys must use double quotes

Valid values include strings, numbers, booleans, arrays, objects, and null

Why JSON Formatting Matters

Clean JSON is easier to debug, share, copy, validate, edit, and understand. Formatting helps you quickly find broken brackets, missing commas, incorrect quotes, and structure problems.

How It Works

Enter raw, minified, or messy JSON into the input box.

Choose options

Select indentation size and enable key sorting if you want organized object keys.

Format or minify

Beautify JSON for reading or minify it for compact storage and fast transfer.

Copy or download

Copy the formatted result or download it as a clean .json file.

A JSON Formatter beautifies JSON by adding indentation, spacing, and line breaks so the data is easier to read.

JSON minify removes extra spaces and line breaks to make the JSON shorter and more compact.

No. The formatting runs in your browser and does not upload or store your JSON input.
