Format, validate, and minify JSON data instantly
Formatted JSON will appear here
Format, validate, and beautify JSON data instantly with our free online JSON formatter. Whether you're a developer working with APIs, debugging JSON responses, or learning JSON syntax, our JSON formatter makes working with JSON data easy and efficient.
JSON (JavaScript Object Notation) is the most popular data format for APIs and web applications. However, JSON data is often minified or poorly formatted, making it difficult to read and debug. Our JSON formatter beautifies JSON by adding proper indentation, line breaks, and syntax highlighting, making it human-readable.
Our JSON formatter also validates JSON syntax, helping you catch errors before they cause problems. It supports JSON5 format, handles large JSON files, and provides features like search, copy, and download formatted JSON.
Format JSON with proper indentation, line breaks, and spacing for easy reading.
Validate JSON syntax and highlight errors with detailed error messages.
Color-coded JSON syntax highlighting for keys, values, strings, and numbers.

Built for developers with features like search, minify, and syntax validation.
Format and validate large JSON files efficiently without performance issues.
JSON is the backbone of modern web development. Well-formatted JSON is easier to read, debug, and maintain. Our JSON formatter helps developers work more efficiently by making JSON data human-readable and catching syntax errors early.
Best practices: Always validate JSON before using it in production. Use formatted JSON for development and debugging, and minified JSON for production to reduce file size. Our tool supports both formatting and minification.
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. JSON is widely used for transmitting data in web applications, APIs, configuration files, and data storage.
A JSON formatter is an essential tool that takes raw, unformatted JSON data and converts it into a properly indented, readable format. This makes it much easier to understand the structure of JSON data, debug issues, and work with complex JSON objects and arrays.
Our JSON formatter tool not only beautifies JSON but also validates it, ensuring that your JSON data is syntactically correct. It helps developers, data analysts, and anyone working with JSON data to quickly format, validate, and understand JSON structures.
Readability: Formatted JSON is much easier to read and understand than minified JSON. Proper indentation and line breaks make it simple to navigate through complex nested structures.
Debugging: When working with APIs or debugging code, formatted JSON helps you quickly identify issues, find specific values, and understand data relationships.
Validation: Our tool automatically validates JSON syntax, catching errors like missing commas, unmatched brackets, or invalid characters before they cause problems in your application.
Documentation: Well-formatted JSON is easier to document and share with team members, making collaboration more efficient.
1. Always Validate JSON
Before using JSON in your application, always validate it to catch syntax errors early. Our formatter automatically validates JSON and highlights errors.
2. Use Consistent Formatting
Maintain consistent indentation (2 or 4 spaces) throughout your JSON files for better readability and team collaboration.
3. Escape Special Characters
Properly escape special characters like quotes, backslashes, and newlines in JSON strings to avoid parsing errors.
4. Use Descriptive Keys
Choose clear, descriptive key names that explain what the data represents, making JSON self-documenting.
Use Ctrl/Cmd + A to select all, then format. Use Tab to indent selected text for manual formatting.
Paste JSON from APIs, files, or clipboard directly into the formatter. The tool automatically detects and formats it.
Invalid JSON is highlighted with error messages showing exactly where the problem is located.
Use the minify feature to compress JSON for production use, reducing file size and improving load times.
Use the search feature to quickly find specific keys, values, or patterns in large JSON files.
Copy formatted JSON to clipboard or download as a file for use in your projects and applications.
