What Is Pretty Print?

JSON Formatting (or Pretty Printing) is the process of taking compressed or disorganized JSON data and adding consistent whitespace, line breaks, and indentation. This makes complex nested data structures significantly easier for developers to read and debug.

Pretty Print Example

Input

{"name":"John","age":30,"active":true}

Output

{
  "name": "John",
  "age": 30,
  "active": true
}

Frequently Asked Questions

What is JSON formatting?

JSON formatting applies structural whitespace to a JSON string without changing its data payload, improving human readability.

Is my JSON uploaded to a server?

No. This tool processes your JSON entirely locally in your browser. Your data never leaves your device.

What is the difference between JSON formatting and minification?

Formatting adds whitespace to make JSON readable, while minification removes all unnecessary whitespace to compress the payload size for faster transmission.
