Online XML Formatter: Beautify, Indent & Clean XML Documents

The Todoal XML Formatter is a fast, browser-native markup beautifier engineered to format unindented, compressed, or minified Extensible Markup Language (XML) documents into clean, human-readable tree structures. When inspecting SOAP web service payloads, RSS feeds, SVG vector assets, Android manifest files, or enterprise configuration manifests, unformatted XML is notoriously difficult to read and debug.

Our client-side formatting engine processes XML documents using browser DOM parsing APIs, automatically normalizing tag indentation (2 spaces, 4 spaces, or tabs), aligning XML element attributes, and preserving CDATA blocks (<![CDATA[ ... ]]>) and XML declaration headers without altering document semantics.

Hierarchical Tree Indentation & Alignment

Maintains consistent indentation depth across deeply nested XML nodes, attributes, closing tags, and self-closing elements with clean vertical alignment.

Protected CDATA & Processing Instructions

Safely preserves XML declarations, namespaces (xmlns), CDATA blocks, and comments without corrupting inner text or escaping markup.

One-Click Download & Instant Copy

Download formatted documents directly as .xml files or copy beautified markup to your clipboard with keyboard shortcuts (Ctrl+Enter).

100% Client-Side In-Memory Privacy

All XML parsing and beautification occurs locally in browser memory. No proprietary enterprise schemas, configuration files, or data feeds are ever transmitted over external networks.

Integrated XML & Data Engineering Suite

Combine XML formatting with syntax validation using our companion XML Validator, or inspect scalable vector graphics with the SVG Viewer. For web markup and data serialization, format HTML with the HTML Formatter, preview HTML in the HTML Previewer, format JSON feeds with the JSON Formatter, and validate JSON schemas with the JSON Validator.

For database and script workflows, format SQL queries using the SQL Formatter, format scripts with the JavaScript Formatter, and test regex patterns with the Regex Tester. Explore all tools in the Developer Tools Suite.

Frequently Asked Questions

Everything you need to know about this browser tool and privacy.

How does the XML formatter format nested tags?
It parses XML node hierarchies, preserving XML declarations (<?xml ...?>), CDATA sections (<![CDATA[...]]>), namespace prefixes (xmlns:), comments, attributes, and self-closing tags with customizable indentation.
Does it validate XML syntax during formatting?
Yes. The formatter checks document well-formedness. If unclosed tags or syntax violations are present, it highlights the parsing issue.
Are XML documents uploaded to a remote server?
No. All formatting logic executes 100% locally inside your web browser.
