JSON Formatter & Validator

What is JSON Formatter & Validator?

JSON (JavaScript Object Notation) is a lightweight data interchange format. This tool helps you format (beautify) messy JSON with proper indentation, validate syntax, and minify (compress) JSON to save space. It's essential for developers working with APIs, configuration files, and data exchange.

How to Use

Step 1: Paste your JSON into the input area.
Step 2: Click "Format / Beautify" to indent and prettify the JSON. Click "Minify" to remove whitespace.
Step 3: If there's a syntax error, the tool will show the error line and message.
Step 4: Copy the formatted/minified output with the "Copy Output" button.

Examples

Input: {"name":"ToolGram","type":"utility"}
Formatted:

{
  "name": "ToolGram",
  "type": "utility"
}

Who Uses JSON Formatters?

• Web Developers – debugging API responses, writing config files.
• Data Analysts – cleaning JSON datasets.
• Backend Engineers – validating JSON schemas.
• DevOps – working with JSON-based infrastructure as code.

Pro Tips

• Use "Format" before editing to make JSON readable.
• Use "Minify" to reduce payload size when sending JSON over network.
• The tool also validates – any syntax error is shown in red.
• You can use the "Clear" button to reset both input and output.
