📋 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 the most popular format for APIs, configuration files, and data storage. JSON uses key-value pairs and supports strings, numbers, booleans, arrays, and nested objects.

💡 JSON Best Practices
- ✓ Use double quotes: JSON requires double quotes for strings, not single quotes
- ✓ No trailing commas: Remove commas after the last item in objects and arrays
- ✓ Proper data types: Use numbers without quotes, booleans as true/false, null for empty values
- ✓ Validate regularly: Always validate JSON before deployment or production use
- ✓ Beautify for readability: Format JSON for easier debugging and maintenance
❓ Frequently Asked Questions
What's the difference between beautify and minify?
Beautify adds indentation and line breaks to make JSON human-readable. Minify removes all whitespace to reduce file size, making it ideal for production environments.
Is my JSON data secure?
Yes! All JSON parsing and formatting happens entirely in your browser. Your data never leaves your device and is not sent to any server.
Can I parse large JSON files?
Yes, our parser can handle large JSON files. However, very large files (>10MB) may take longer to process depending on your device's performance.
What errors does the parser detect?
The parser detects syntax errors like missing quotes, trailing commas, invalid characters, unclosed brackets, and incorrect data types. Error messages show the exact location of the issue.
Can I use this for API testing?
Absolutely! This tool is perfect for testing API responses, validating request payloads, and formatting JSON data from API calls.
