XML enforces a stricter structural rule than most formats, every opening tag needs a matching closing tag with the exact same name, and a raw ampersand or angle bracket inside actual content has to be escaped as an entity or the parser fails outright, mistakes that are easy to introduce by hand and genuinely hard to spot in a wall of unformatted markup. This tool formats and validates XML, applying proper indentation with syntax highlighting and flagging a specific structural error, an unescaped character, a mismatched tag, the moment something breaks.

Useful for pretty-printing a minified XML API response into something actually readable, catching a mismatched or unclosed tag before it breaks a downstream parser, or validating a hand-edited XML config file before it gets deployed.

Quick answers for XML Formatter

How does it detect invalid XML?
It parses your input with the browser's built-in DOMParser and checks for a parsererror node, flagging the specific parsing failure instead of just failing silently.
Can I switch between formatting and minifying?
Yes, Format and Minify mode tabs let you either pretty-print the XML with indentation or collapse the whitespace between tags into a single compact line.
What indentation options are available?
You can choose between 2-space and 4-space indentation, and attribute values and text content are properly escaped for characters like &, <, and " during formatting.
