Frequently Asked Questions About JSON to XML Converter
Get answers to common questions about JSON to XML Converter
How do I handle attributes when converting to XML?
Use the @_ prefix in your properties to indicate XML attributes. For example, {"@_id": "123", "#text": "content"} converts to <element id="123">content</element>. This notation ensures proper attribute mapping during conversion.
What happens to arrays during XML conversion?
Arrays are converted to repeated XML elements with the same name. Each array item becomes a separate element, maintaining the data structure while following XML standards. Large arrays (1000+ items) will generate many XML elements.
How does the converter handle invalid XML element names?
The converter automatically sanitizes property names to make them XML-compliant. Special characters are replaced with underscores, and names starting with non-letters get an underscore prefix. Reserved XML names are also handled safely.
Is the generated XML compliant with XML 1.0 standards?
Yes! The converter uses xmlbuilder2 to generate well-formed XML 1.0 compliant documents with proper UTF-8 encoding, character escaping for special characters, and correctly structured elements and attributes.
Can the converter detect and handle circular references?
Absolutely! The converter automatically detects circular references in your data and prevents infinite loops during processing. If circular references are found, you'll get a clear error message asking you to resolve them before conversion.
Is my data processed securely?
Yes! All conversion happens entirely in your browser using client-side JavaScript. No data is uploaded to servers, ensuring complete privacy and security for your configuration files, API data, or sensitive information.
