How to Format JSON - Step by Step Guide

Step 1

Input Your JSON Data

Let's get your JSON into the formatter! You have several convenient options:

•
Paste directly: Copy your API response or JSON data and paste it into the input editor
•
Upload a file: Click "Upload" to select a .json or .txt file from your computer
•
Try the sample: Click "Sample" to load example data and see how the formatter works 😊

Example: Unformatted JSON Input

Here's what messy, unformatted JSON looks like:

{"name":"Sarah Chen","email":"sarah@company.com","age":29,"department":"Marketing","skills":["SEO","Content Strategy","Analytics"],"active":true,"projects":[{"id":"PROJ-001","name":"Website Redesign","status":"active","budget":15000},{"id":"PROJ-002","name":"Social Media Campaign","status":"completed","budget":8500}]}
Step 2

Automatic Formatting & Validation

The magic happens instantly! 🎉 As soon as you input JSON, the formatter automatically:

•
Validates syntax: Checks for errors and highlights issues with helpful suggestions
•
Adds proper indentation: Makes nested objects and arrays easy to read
•
Syntax highlighting: Color-codes different elements for better readability

The same JSON, now properly formatted and readable: ✨

{
  "name": "Sarah Chen",
  "email": "sarah@company.com",
  "age": 29,
  "department": "Marketing",
  "skills": [
    "SEO",
    "Content Strategy",
    "Analytics"
  ],
  "active": true,
  "projects": [
    {
      "id": "PROJ-001",
      "name": "Website Redesign",
      "status": "active",
      "budget": 15000
    }
  ]
}
Step 3

Choose Format Options

Customize your output based on your needs! 🎛️ The formatter gives you control over how your JSON appears:

•
Pretty format: Default beautified JSON with proper indentation (2 spaces)
•
Minify option: Click "Minify" to compress JSON into a single line for production use
•
Syntax highlighting: Color-coded elements make it easy to spot different data types
Step 4
