XML Formatter Online – Format Messy XML in One Click

This tool takes hard-to-read XML and lays it out cleanly. Paste your XML into the box, click Format XML, and the tool rewrites it with proper indentation and line breaks so you can actually read it. It works in any modern browser, with no signup and nothing to install.

Make XML Easy to Read

Minified or machine-generated XML usually arrives as one unbroken block. The formatter adds consistent spacing and indentation, so nested elements line up and the structure becomes obvious at a glance. That makes it far quicker to find the element you care about.

Works With Common XML-Based Files

Because it formats XML itself rather than one specific schema, it handles the common XML-based formats too, including WSDL, SOAP, XSD, RSS, SVG, RDF and POM files. These are all XML underneath, so the formatter treats them the same way it treats any other XML file.

How to Format XML Here

Paste or type your XML into the input box.
Click Format XML.
Select the indented output and copy it wherever you need it.

Result: the same XML, re-indented and readable, ready to review, copy, or paste into your editor.

What Is XML?

XML (Extensible Markup Language) is a text format used to store and share data in a structured way. It is not tied to one industry, so you will find it across many systems and file types.

Why XML Is Used

XML uses custom tags to keep data organized and clear. It helps you:

Store data and metadata
Define simple values like dates and IDs
Build complex data structures
Follow rules so software can read and process data correctly

Common Uses of XML

XML is often used for structured lists of information such as settings, records, feeds, and integrations. You will also see it in web services, configuration files, and document formats.
