Frequently Asked Questions
Is my JSON data secure?
Absolutely. All processing happens 100% in your browser. Your data is never sent to any external server.
What is JSON Minification?
Minification removes unnecessary whitespace and indentation from your JSON, reducing file size for production use.
Why is my JSON invalid?
Common reasons include missing quotes around keys, trailing commas, or using single quotes instead of double quotes. Our validator will help identify these issues.
