Frequently Asked Questions

How do I convert XML to JSON online?
Simply paste your XML data into the input field, configure your conversion options (attribute handling, formatting, indentation), and click "Convert XML to JSON". The tool will automatically transform your XML into JSON format with proper attribute and namespace handling.
Can I convert JSON back to XML?
Yes! The converter supports bidirectional conversion. Switch the direction to "JSON → XML" and paste your JSON data. The tool will convert it back to properly formatted XML, preserving structure and attributes.
How are XML attributes handled in JSON?
XML attributes are converted to JSON properties with a configurable prefix (default "@_"). For example, <book id="1"> becomes {"@_id": "1"} in JSON. You can customize the prefix, parse attribute values as numbers/booleans, and choose to include or exclude attributes.
Can the converter handle complex nested XML?
Yes! The converter uses fast-xml-parser library to handle complex nested XML structures, including multiple levels of nesting, arrays, attributes, and namespaces. It preserves the hierarchy and converts it to equivalent JSON structure.
What output formats are supported?
The converter supports three output formats: JSON (standard), YAML (for configuration files), and XML (for JSON to XML conversion). You can choose your preferred format and configure formatting options like indentation and pretty printing.
Is XML namespace conversion supported?
Yes! The tool can handle XML namespaces. You can choose to remove namespace prefixes for cleaner JSON output or preserve them for full structure fidelity. This is useful for SOAP APIs and complex XML schemas.
Is my XML/JSON data secure and private?
Absolutely! All conversion happens entirely in your browser using client-side JavaScript. No data is sent to our servers or stored anywhere. Your XML and JSON data remains completely private and secure throughout the conversion process.
What is the maximum file size supported?
You can upload XML or JSON files up to 10MB. The input text limit is 1MB. This is sufficient for most use cases including API responses, configuration files, and data exports. For larger files, consider splitting them into smaller chunks.
