JSON Formatter
📊 JSON Formatter
Validate and beautify JSON data for better readability.
Working with API data can be messy. Raw JSON often comes as a single, unreadable line of text. TinyView's JSON Formatter is the ultimate tool for developers to clean, format, and validate JSON data instantly. Best of all, your data stays in your browser—no server uploads required.
Key Features:
✨ Beautify: Turn "minified" JSON into a pretty, readable structure with 2 or 4-space indentation.
📦 Minify: Shrink your JSON data to its smallest size for efficient API requests.
🛡️ Validator: Instantly detect errors in your JSON structure with clear error messages.
🔒 Local & Secure: Since processing happens locally, it's safe to format sensitive data or internal API responses.
How to Use:
Input: Paste your raw JSON text into the "Raw JSON" box.
Format: Click "Beautify" to make it readable, or "Minify" to compress it.
Check: The tool will automatically tell you if your JSON is "Valid" or "Invalid."
Copy: Click "Copy Result" to use your perfectly formatted JSON anywhere.
