JSON Tools – Format, Validate, Compare & Convert

What is JSON?

JSON (JavaScript Object Notation) is a lightweight data-interchange format that's easy for humans to read and write and easy for machines to parse and generate. It's widely used for APIs, configuration files, and data storage.

Key Features

• Real-time Validation: Instantly validates your JSON with detailed error messages showing line and column numbers
• Flexible Formatting: Beautify with customizable indentation (2/4 spaces or tabs) or minify to reduce file size
• Sort Keys: Alphabetically organize object keys for better readability and consistency
• File Support: Upload JSON files or paste directly into the editor
• Export Options: Copy to clipboard or download formatted output as a file

When to Use

• Validate API responses or request payloads
• Debug JSON syntax errors quickly with precise error locations
• Format minified JSON for better readability
• Standardize JSON structure across your project
• Clean up JSON before committing to version control

Privacy & Security

All JSON processing happens locally in your browser. No data is sent to any server or stored anywhere. Your JSON data remains completely private and secure.
