Frequently asked questions

Does this tool rigorously validate the XML schema?

It formats the structural depth, but it does not run a strict schema validation pass. Malformed XML may yield imperfect formatting.

Will formatting alter any of my attribute values?

No. Only whitespace located specifically between structural elements is adjusted. Your core content remains untouched.

Can it handle massive XML documents?

It processes typical documents perfectly within the browser. Gigabyte-sized XML databases should be handled with terminal tools.
