What Is an XML Beautifier?

XML uses tags to structure data. Minified or poorly indented XML—often a single line from APIs or config exports—is hard to read. An XML Beautifier adds indentation and line breaks so you can see the hierarchy. Unlike a basic formatter, this tool lets you set the indent size (1–8 spaces) to match your project's style. The W3C XML specification defines the syntax.

Beautification runs entirely in your browser using the DOMParser. Nothing is sent to a server, so it's safe to use with production data or sensitive configuration.

How to Use This Tool

1

Paste or Upload XML

Copy your XML and paste it into the left editor. You can also click Upload to load a .xml file from your computer. Set Indent Size (1–8 spaces) in the options bar to match your preferred style. The Sample button loads example data if you want to test things out.

2

View Beautified Output

The right panel shows the indented XML. Invalid XML will show an error—fix it first using the XML Validator. For extracting specific values from large XML, the XPath tool works well alongside this.

3

Copy or Download

Use <strong>Copy</strong> to put the result on your clipboard, or <strong>Download</strong> to save it as a file. For minifying, use XML Minifier. For converting to JSON, use XML to JSON.

When XML Beautification Helps

SOAP and REST APIs often return XML as a single compressed line. Pasting the response here makes nested elements visible. Config files like pom.xml or web.config with inconsistent indentation are hard to review—beautifying gives you a consistent layout. For RSS or Atom feeds that fail validation, formatting here helps you spot the exact error.

Frequently Asked Questions

Beautifier vs Formatter?

Both indent XML. The Beautifier lets you choose indent size (1–8 spaces); the Formatter uses a fixed default. Functionally similar—pick the one that matches your workflow.

Is my data private?

Yes. Beautification runs entirely in your browser using JavaScript. No data is sent to any server. You can confirm this by opening your browser's Network tab while using the tool.

What about XML namespaces?

Namespace declarations and prefixes are preserved. The beautifier only changes whitespace, not structure or content.
