Frequently Asked Questions
How are XML attributes handled?
By default, attributes are prefixed with `@_` (e.g., id='1' becomes '@_id': 1) to distinguish them from standard tags, ensuring no data loss during conversion.
Is my XML data secure?
Yes. All conversion happens locally in your browser using JavaScript. No data is ever uploaded to our servers, making it safe for sensitive enterprise configuration parsing.
Does it support nested tags and arrays?
Yes. The converter intelligently identifies repeating elements and groups them into JSON arrays, while maintain the hierarchy of nested tags.
What is the maximum file size supported?
Since the tool runs in your browser, it can handle several megabytes of XML data depending on your available RAM. For extremely large datasets (100MB+), specialized streaming parsers are recommended.
Can I convert SOAP responses to JSON?
Absolutely. This tool is designed to help developers modernize legacy SOAP-based services by transforming the XML-encoded body into a format easily consumable by React or Vue applications.
Are CDATA sections supported?
Yes, the parser correctly identifies and extracts content from `<![CDATA[...]]>` blocks, preserving the literal text inside without escaping.
