Paste your raw, minified, or broken XML into the editor above and instantly get clean, properly indented, human-readable output. Our free XML formatter works entirely in your browser — no installation, no account, no waiting. Whether you're debugging a SOAP response, cleaning up a configuration file, or just trying to make sense of a compressed XML string, you're in the right place.
XML (eXtensible Markup Language) is a structured, text-based format designed to store and transport data in a way that is both human-readable and machine-readable. Unlike HTML, which is used to display data, XML is used to describe and carry data — the tags are not predefined, and you define your own structure to suit your needs.
Originally standardized by the W3C in 1998, XML became the backbone of the early web services era and remains widely used today in enterprise systems, document formats, configuration files, and data interchange between systems. Formats like RSS, SVG, Microsoft Office files (.docx, .xlsx), SOAP APIs, and Android layout files are all built on XML.
A basic XML document looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<bookstore>
<book category="fiction">
<title lang="en">The Great Gatsby</title>
<author>F. Scott Fitzgerald</author>
<year>1925</year>
<price>12.99</price>
</book>
<book category="non-fiction">
<title lang="en">Thinking, Fast and Slow</title>
<author>Daniel Kahneman</author>
<year>2011</year>
<price>15.99</price>
</book>
</bookstore>XML is strict about structure — every opening tag must have a closing tag, attributes must be quoted, and the document must have exactly one root element. A single violation makes the entire document invalid, which is why having a reliable XML formatter and validator is so important.
An XML formatter (also called an XML beautifier or XML pretty printer) is a tool that takes raw or compressed XML text and restructures it into a clean, indented, human-readable format with consistent spacing and line breaks.
When XML data is transmitted over a network or stored in a file for efficiency, it is often minified — all unnecessary whitespace is removed. This is fine for machines but nearly unreadable for humans. An XML formatter restores that structure, making the data easy to scan, debug, and understand.
For example, this minified XML:
becomes this after formatting:
<?xml version="1.0"?>
<user>
<id>101</id>
<name>Alice</name>
<roles>
<role>admin</role>
<role>editor</role>
</roles>
<active>true</active>
</user>The data is identical — but the formatted version reveals the structure at a glance.
Click Beautify to instantly transform any raw or minified XML into neatly indented, well-structured output. Choose your preferred indentation style — 2 spaces, 4 spaces, or 8 spaces.
Our real-time XML validator checks your document for well-formedness against the W3C XML specification. Catch missing tags, unclosed attributes, or missing root elements instantly.
Use the Minify option to strip all whitespace and produce the smallest possible XML string. Smaller payloads mean faster API calls and lower bandwidth costs.
The editor uses full syntax highlighting to color-code tags, attributes, values, comments, and declarations. Easily scan large, deeply nested XML documents.
Need your XML data in a different format? Convert XML to JSON, YAML, CSV / TSV, or Plain Text. Transform data for modern APIs or spreadsheets.
All formatting, validation, and conversion happens entirely in your browser using JavaScript. Your XML data is never uploaded to our servers.
Formatting XML takes less than 10 seconds with our tool:
Copy your raw, minified, or malformed XML and paste it into the input editor on the left. Alternatively, click "Open File" to upload an .xml file.
Select your preferred indentation (2, 4, or 8 spaces), then click the action you need: Beautify, Minify, or Validate.
Formatted output appears instantly in the right-hand panel with full syntax highlighting. Errors are highlighted with specific line numbers.
Click the copy icon to copy the result to your clipboard, or click Download to save it as a file. Convert to other formats if needed.
Every opening tag must have a matching closing tag, and they must be properly nested.
A valid XML document must have exactly one root element that wraps all other elements.
All XML attribute values must be enclosed in quotes.
Characters like <, >, &, ", and ' must be escaped when used inside element content.
XML tags are case-sensitive. <Name> and <name> are treated as completely different elements.
Most expressive. Supports attributes, namespaces, schemas (XSD). Best for enterprise systems, SOAP, document formats.
Lighter, concise. Native in JS. Standard for modern REST APIs and web apps. Simpler structure.
Most human-readable. Widely used for configuration (Kubernetes, Ansible). Indentation-sensitive.
Backend & Enterprise Developers debug SOAP services and validate framework configs.
Android Developers format layout and manifest files.
QA Engineers inspect XML-based API responses.
DevOps Engineers work with XML configs for CI/CD and servers.
Data Engineers validate XML during ETL processes.
Technical Writers format XML outputs for documentation.
Students learn XML structure interactively.
