JSON FORMATTER & VALIDATOR
Why Use a JSON Formatter?
JSON (JavaScript Object Notation) is the language of modern web data. However, API responses and config files often come "minified" (squashed into one line), making them impossible to read. This tool instantly formats messy JSON into a structured, readable tree.
Key Functions
- Beautify: Adds proper indentation (2 spaces) and line breaks to make code readable.
- Minify: Removes all unnecessary whitespace to reduce file size for production use.
- Validate: Checks for syntax errors (like missing commas or quotes) and alerts you immediately.
How It Works
This tool uses the native JavaScript JSON.parse() and JSON.stringify() methods directly in your browser. This ensures maximum speed and compatibility while guaranteeing that your data remains private.
Frequently Asked Questions
Is my JSON data secure?
Yes. This tool runs 100% in your browser using JavaScript. Your JSON data is never sent to our servers, ensuring complete privacy for sensitive configs or API responses.
What is Minification?
Minification removes all unnecessary whitespace, newlines, and indentation from the JSON. This reduces file size for data transmission but makes it harder for humans to read.
Why is my JSON invalid?
Common errors include missing quotes around keys (e.g., {key: "value"} instead of {"key": "value"}), trailing commas after the last item, or unclosed brackets. This tool will alert you if the syntax is incorrect.
