🔄 Understanding JSON and XML
JSON (JavaScript Object Notation) is a lightweight, human-readable data format widely used in modern web APIs. XML (eXtensible Markup Language) is a structured markup language common in enterprise systems and legacy applications. Both serve data exchange purposes but with different syntax and use cases.

❓ Frequently Asked Questions
When should I use JSON vs XML?
JSON is ideal for web APIs, JavaScript applications, and modern systems due to its simplicity. XML excels in document-centric applications, enterprise systems, and scenarios requiring schemas and namespaces.
Are XML attributes preserved?
Yes, XML attributes are converted to a special "@attributes" property in JSON, ensuring no data loss during conversion.
Can I convert large files?
The tool handles reasonably large files efficiently. For extremely large datasets (>10MB), consider splitting them into smaller chunks for optimal performance.
Is the conversion lossless?
The converter preserves data structure and content. However, some XML-specific features like processing instructions may not have direct JSON equivalents.
Is my sensitive data safe?
Absolutely! All conversions occur entirely in your browser using JavaScript. No data is transmitted to our servers or any third parties.
