A JSON Formatter is an online tool that helps you format, beautify, and validate your JSON data. JSON (JavaScript Object Notation) is one of the most popular data formats used for API communication and configuration files. Raw JSON is often compact and hard to read — our JSON Formatter displays it in a clear, indented, and color-coded structure for easy understanding.
Whether you’re a developer debugging an API response or someone exploring structured data, this JSON Formatter tool provides a simple, mobile-friendly way to view, validate, and copy your data.
.json file.Example:
Input:
{"name":"John","age":30,"city":"New York"}
Output (formatted):
{
"name": "John",
"age": 30,
"city": "New York"
}
