About XML Beautifier

XML that's been minified, generated by an API, or pasted from a log file often arrives as one dense unreadable line — impossible to actually review or debug without reformatting it first. This tool validates your XML and reformats it with consistent two-space indentation, making the document's nesting structure immediately readable.

Validation happens via the browser's built-in DOMParser before formatting, so malformed XML is caught and flagged with a clear error rather than silently producing broken output. Once validated, the tool walks the tag structure and rebuilds it with proper indentation reflecting each element's nesting depth.

This is a common step when debugging an API response, reviewing a configuration file, or just making sense of XML data that's been stripped of whitespace for transmission efficiency — reformatting it back to readable structure takes one paste.

How it works

  1. Paste your XML. Minified, single-line, or otherwise unformatted.
  2. Validation runs automatically. Malformed XML is flagged with a clear error.
  3. Copy the formatted result. Properly indented, readable XML.
