Free JSON Formatter & Validator
Instantly beautify, minify, and validate your JSON data. Keep your data structured and error-free.
What is a JSON Formatter?
JSON (JavaScript Object Notation) is a lightweight data-interchange format. While machines read it easily, unformatted JSON can be a nightmare for developers to navigate. Our JSON Formatter is a free online tool that converts messy, compressed JSON into a clean, human-readable format with proper indentation and structure.
How to Use the JSON Formatter
- 1 Paste JSON: Paste your raw JSON data into the left input panel.
- 2 Select Action: Click "Beautify" to format or "Minify" to compress your data.
- 3 Export: Use the "Copy" or "Download" buttons to save your processed JSON.
Frequently Asked Questions
Is my data safe?
Absolutely. We process your data locally in your browser whenever possible, and we never store your data on our servers. Your security and privacy are our top priorities.
What happens if my JSON is invalid?
Our tool includes a built-in JSON Validator. If you try to format invalid data, the tool will highlight the error and provide a specific message explaining what went wrong and where.
Why should I minify my JSON?
Minification removes all unnecessary whitespace like spaces, tabs, and newlines. This reduces the file size, leading to faster data transmission and improved performance for your web applications.
