Frequently Asked Questions About XML to JSON Converter
Get answers to common questions about XML to JSON Converter
How does the converter handle XML attributes and mixed content?
XML attributes are mapped to properties with @_ prefix notation, making them easily identifiable. Mixed content (text + elements) is handled by preserving text in #text while maintaining the element structure. This ensures no data is lost during conversion.
What happens to CDATA sections during conversion?
CDATA sections are preserved as-is during conversion. The parser maintains the original text content without interpreting it as markup, ensuring that embedded scripts, HTML, or other special content remains intact in the result.
How does the tool handle XML namespaces?
The converter detects XML namespaces and preserves them in the element names. While it doesn't perform complex namespace processing, it maintains namespace prefixes where present, allowing you to identify the source namespace in the converted result.
Can I convert large XML configuration files?
Yes! The converter handles XML files up to 10MB efficiently. It uses fast-xml-parser for reliable processing of large configuration files, data exports, and API responses while maintaining good browser performance.
How accurate is the data type conversion from XML to structured objects?
The converter uses intelligent type inference to convert values to appropriate types (strings, numbers, booleans). Numeric values and boolean attributes are automatically detected and converted while preserving the original structure.
Is my data processed securely?
Absolutely! All processing happens entirely in your browser using client-side JavaScript. No data is uploaded to servers, ensuring complete privacy and security for your configuration files, data exports, or API responses.
