What is a JSON Formatter?

A JSON Formatter beautifies minified or compressed JSON into a human-readable indented format. It also validates JSON syntax, minifies pretty-printed JSON for network transmission, and helps you spot errors like missing commas, mismatched brackets, or incorrect data types.

How to Use It

  1. 1Paste your JSON string into the input area, or upload a .json file
  2. 2Click 'Format' to prettify with proper indentation, or 'Minify' to compress
  3. 3Validation errors are highlighted with the line number and description
  4. 4Use the copy button to copy the formatted output to your clipboard

Example

{"name":"Ravi","age":30,"city":"Mumbai"} formatted becomes: { "name": "Ravi", "age": 30, "city": "Mumbai" }

Why Use It

  • Debug API responses and config files by making them readable
  • Validate JSON before sending it to an API or saving to a database
  • Minify JSON to reduce payload size for web applications
  • Quickly inspect deeply nested JSON structures with tree-like indentation
