JSON Formatter

What is JSON?

JSON (JavaScript Object Notation) is a lightweight, text-based data interchange format. It is easy for humans to read and write and easy for machines to parse and generate. JSON is built on two universal data structures:

• Object — an unordered collection of key/value pairs enclosed in {}
• Array — an ordered list of values enclosed in []

JSON supports six value types: string, number, boolean, null, object, and array. It is the dominant format for REST APIs, configuration files, and data storage.

{
  "name": "Alice",
  "age": 30,
  "active": true,
  "tags": ["admin", "user"],
  "address": null
}

Tool Features

• Format — formats JSON with 2-space indentation for readability
• Minify — strips all whitespace to produce the most compact representation
• Tree View — explore your JSON as a collapsible tree with search; nodes deeper than 2 levels start collapsed
• Edit Mode — expands the input editor to full width for focused editing
