What this tool does

Validate and reformat XML instantly. Paste a messy single-line XML response from an API, a minified config file, or a copied fragment, and this tool beautifies it into a readable, properly indented document. Invalid XML is reported with the exact line number so you can jump to the problem.

What's preserved

  • Comments<!-- ... --> are kept in place.
  • CDATA blocks — content inside <![CDATA[...]]> is kept verbatim.
  • Processing instructions<?xml-stylesheet ...?> and similar.
  • Attribute order — left in the order you wrote them.
  • XML declaration — the <?xml version=...?> line. Toggle on/off.

Common XML mistakes

  • Unclosed tags — every <tag> needs a matching </tag> or must be self-closing (<br/>).
  • Unescaped special characters in text — use &amp;, &lt;, &gt;, &quot;, &apos;.
  • Attribute values without quotes — XML requires attr="value". HTML lets you drop them; XML does not.
  • Multiple root elements — an XML document must have exactly one root element.
  • Case-sensitivity<Item> and <item> are different tags in XML.

When to minify XML

Minify when storage or network transfer cost matters — API responses, SVG assets shipped to browsers, configuration embedded in HTML. For human editing and version-control diffs, keep it pretty-printed.
