XML File Tools, With the Namespaces Left Intact

A browser-local tool for viewing, formatting, and validating XML files or pasted XML.

Landing page captured for the 2026-09-20 issue.

For: People inspecting, formatting, or validating XML
Worth noticing: It preserves namespace declarations and rejects DOCTYPE input rather than flattening XML into ambiguous object keys.

Field notes

The page accepts a file up to 25 MB, drag-and-drop input, or pasted XML, then offers formatting and validation in the browser. Its stated handling is more specific than a generic formatter: qualified names and namespace declarations remain visible, malformed input receives a line-aware error, and DOCTYPE declarations are rejected. The site notes that document contents stay local, while ordinary page and asset requests still reach the hosting provider.
