Json Minifier

JSON Minifier & Formatter


Our online JSON tool helps you minify, format, and validate your JSON data. Whether you're working with APIs, configuration files, or data storage, this tool instantly transforms JSON between compact and human-readable formats.

What is JSON?

JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate.

Unminified JSON might look like this:

{ "name": "John Doe", "age": 30, "address": { "street": "123 Main St", "city": "New York" }, "hobbies": ["reading", "hiking"] }

Step by Step Guide

  • Click "Process" to transform your JSON
  • Review the output with syntax highlighting
  • Download or copy the final result

Sample JSON for Testing
// Unminified JSON
{
  "productId": 12345,
  "productName": "Wireless Mouse",
  "price": 29.99,
  "tags": ["electronics", "peripheral"],
  "stock": {
    "warehouse": 150,
    "retail": 35
  }
}

// Minified Result:
{"productId":12345,"productName":"Wireless Mouse","price":29.99,"tags":["electronics","peripheral"],"stock":{"warehouse":150,"retail":35}}

// Formatted Result (2-space indent):
{
  "productId": 12345,
  "productName": "Wireless Mouse",
  "price": 29.99,
  "tags": [
    "electronics",
    "peripheral"
  ],
  "stock": {
    "warehouse": 150,
    "retail": 35
  }
}
