FAQs
What is JSON validation?
JSON validation checks if your JSON data follows the correct syntax and structure. It helps identify errors like missing commas, brackets, or invalid data types.
Is this tool secure to use?
Yes, our tool processes all data locally in your browser. We don't store or transmit any of your JSON data, ensuring complete privacy and security.
What is JSON Schema validation?
JSON Schema validation checks if your JSON data conforms to a specific schema or structure. It validates data types, required fields, and format requirements.
Are there any size limitations for JSON files?
While there's no strict limit, very large JSON files (over 10MB) may slow down your browser. For optimal performance, we recommend keeping files under 5MB.
Can I validate JSON from a URL?
Yes, you can fetch and validate JSON from any public URL. Simply paste the URL and our tool will fetch the JSON data for validation.
What's the difference between minify and format?
Formatting adds proper indentation and spacing to make JSON readable, while minifying removes all unnecessary whitespace to reduce file size.
Does this tool work on mobile devices?
Yes, our JSON validator and formatter is fully responsive and works on both desktop and mobile devices.
Can I save my validation history?
Yes, the tool automatically saves your recent JSON files in your browser's local storage for quick access.
