Frequently Asked Questions

Find Quick Answers

What formats are supported?

The tool accepts XML documents as plain text or file uploads and can output XML in formatted or minified forms; when converting, a JSON representation is produced. It handles UTF-8 encoded input by default.

Can I validate against a schema?

Yes, you can provide an XSD or DTD alongside the XML; the tool validates structure and content, returning a report with error locations (line and column) and severity to aid debugging.

Can I convert to JSON?

Yes, the XML can be parsed into a JSON representation where elements map to objects and attributes to properties; you can review the JSON output and use it for APIs or data pipelines.

Is batch processing supported?

Single-document processing is the default per run; batch processing can be achieved via the API or by running multiple documents sequentially, with each result exported separately.
