JSON Formatter

What is JSON Formatter?

A JSON formatter transforms compact or poorly formatted JSON into a human-readable structure with consistent indentation, line breaks, and proper nesting. JSON (JavaScript Object Notation) is the most widely used data interchange format for web APIs, configuration files, and data storage. Raw API responses and minified JSON files are difficult to read and debug without proper formatting. This tool parses your JSON input, validates its syntax, and outputs a cleanly indented version that makes nested objects, arrays, and key-value pairs easy to understand at a glance. Whether you are debugging API responses, reviewing configuration files, or preparing data for documentation, proper JSON formatting saves time and reduces errors.

How to Use JSON Formatter

1. Paste your JSON data into the input area.
2. Click Format to beautify with 2-space indentation.
3. Click Minify to compress JSON into a single line.
4. Copy the formatted output to your clipboard.

Examples

{"name":"John","age":30,"address":{"city":"NYC","zip":"10001"}}

[{"id":1,"title":"Hello"},{"id":2,"title":"World"}]

Common Use Cases

• Formatting API responses for debugging and analysis
