Format & Validate XML Online

ToolSnak's XML Formatter instantly beautifies messy or minified XML with proper indentation and line breaks. It also validates whether your XML is well-formed and can minify XML by stripping unnecessary whitespace — all without uploading anything to a server.

Key Features

  • Beautify XML with 2 spaces, 4 spaces, or tab indentation
  • Minify XML by removing all unnecessary whitespace
  • Validate XML using the browser's built-in DOMParser
  • Shows the exact error message for invalid XML
  • Upload XML, HTML, or SVG files via drag-and-drop
  • Copy formatted output or download as .xml
  • 100% browser-based — your XML is never sent to a server

How to Use

  1. Upload an XML file or paste your XML into the text area.
  2. Click 'Format / Beautify' to prettify with your chosen indentation.
  3. Or click 'Minify' to strip all whitespace.
  4. Click 'Validate' to check if the XML is well-formed.
  5. Copy the output or download it as an .xml file.

Got Questions? We have you covered

Well-formed XML follows the structural rules of the XML specification: all tags are properly opened and closed, attributes are quoted, and there is a single root element. The validator uses the browser's DOMParser to check this.

No. The validator checks structural well-formedness only, not schema validity. For XSD validation you would need a server-side tool.

Yes. The file upload accepts .xml, .html, .svg, and .xsd files. All are treated as XML text and formatted the same way.

There is no hard limit imposed by the tool. Very large files (>10 MB) may take a moment to process since all work is done in your browser.
