Online JSON Formatter & Beautifier

Clean, format, and validate your JSON data instantly with TinyTool's Online JSON Formatter. Whether you are a developer debugging an API response or a data analyst organizing nested structures, our tool provides a fast, secure, and reliable way to make JSON human-readable.

Why use our JSON Formatter?

JSON (JavaScript Object Notation) is the most popular data format for APIs and modern web applications. However, raw JSON often comes as a single line of text, making it nearly impossible to read. Our tool helps you:

• Improve Readability: Instantly turn minified JSON into a beautiful, indented structure.
• Validate Data: Automatically detect syntax errors and find where your JSON is broken.
• Minify for Production: Reduce file size by removing whitespace for faster data transfer.
• Privacy Guaranteed: Your data is processed entirely in your browser. We never store or transmit your JSON content to any server.

Key Features

1. Custom Indentation: Choose between 2-space or 4-space indentation based on your preference.
2. One-Click Minify: Quickly compress your JSON for usage in configuration files or code.
3. Error Highlighting: Get clear feedback if your JSON contains syntax errors like trailing commas or missing quotes.
4. Copy to Clipboard: Easily move your formatted data back to your code editor or project.

How to use the JSON Formatter

1. Paste: Copy your JSON string and paste it into the "Input JSON" area.
2. Format: Click "Beautify" to expand the structure or "Minify" to compress it.
3. Result: Your formatted JSON will appear in the output window instantly.
4. Fix: If you see an "Invalid JSON" error, check the feedback to fix your syntax.
