How Does JSON Formatting Work?
JSON formatting takes compact or minified JSON and adds proper indentation, line breaks, and spacing to make it human-readable. The formatter parses the JSON structure and applies consistent formatting rules.
Syntax Validation
Validates JSON syntax before formatting, ensuring the data structure is correct.
Indentation
Adds consistent indentation (typically 2 spaces) to show the hierarchical structure of nested objects and arrays.
Minification
Removes all unnecessary whitespace to create compact JSON for production use, reducing file size.
Using JSON in JavaScript:
const data = {"name":"John","age":30};
const formatted = JSON.stringify(data, null, 2);
console.log(formatted);{
"name": "John",
"age": 30
} Format JSON with proper indentation using JSON.stringify
const data = {"name":"John","age":30};
const minified = JSON.stringify(data);
console.log(minified);{"name":"John","age":30} Create compact JSON by omitting spacing parameter
