JSON Formatter
Format, validate, and minify your JSON data instantly.
What is JSON Formatter?
JSON Formatter is a free online tool designed to help developers format, validate, and minify JSON data. It makes compact JSON readable (beautify) or compacts formatted JSON (minify) for production use. JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate.
Why use our JSON Formatter?
Working with nested or minified JSON can be challenging. Our tool provides an instant way to visualize the structure of your data. Key benefits include error detection with line numbers, syntax highlighting for better readability, and local processing that ensures your sensitive data never leaves your computer.

- Instant Formatting: Convert messy strings into neatly indented JSON.
- Minification: Compress JSON objects into a single line to save bandwidth.
- Live Validation: Identify syntax errors like missing commas or mismatched brackets immediately.

Frequently Asked Questions
Is my data safe?
Yes, absolutely. Our JSON Formatter works entirely on the client-side. We do not store or transmit your data to any external servers.
What is the maximum file size supported?
There is no hard limit, but for the best performance, we recommend using it for JSON files under 5MB. Very large files might slow down your browser.
Can I use it to validate JSON?
Yes, our tool automatically validates your input. If the JSON is invalid, an error message with details will be shown.
