Frequently Asked Questions

Common questions for the selected tool, explained clearly so you can move faster.

What XML problems can this tool detect?+

This validator checks for mismatched tags, invalid characters, missing closing tags, and general XML syntax errors.

Why does XML-to-JSON sometimes show no output?+

The converter first validates XML syntax via DOMParser. If your XML is malformed, namespaced, or missing a root element, it shows an error instead. For large responses, use the vertical scroll bars in input/output panes and ensure the XML is well-formed.
