About the XML Viewer
Paste an XML document to format it with clean indentation, or minify it to a single line. Invalid XML is detected and reported so you can spot structural problems quickly.

Frequently asked questions
Does it validate XML?
Yes. It parses the document and reports a message if the XML is not well-formed.
What's the difference between format and minify?
Format adds indentation and line breaks for readability; minify removes whitespace between tags for the smallest output.
Is my XML uploaded?
No. All processing happens locally in your browser.
Is it free?
