XML Formatter
Beautify or minify XML with advanced formatting options. Validate, sort attributes, customize indentation, and analyze XML structure with detailed statistics.

Recommended Settings
Formatting Modes
- •Use beautify mode for development, debugging, and reading XML configuration files
- •Use minify mode for production to reduce file size and bandwidth usage
- •Toggle between modes instantly to compare size differences
Configuration Options
- •Choose 2-space indentation for most projects (follows common conventions)
- •Enable 'Sort attributes alphabetically' for consistent version control diffs
- •Preserve comments in beautify mode for maintaining documentation
- •Use self-closing tags for empty elements to follow XML best practices
Pro Tips
- •Paste XML directly - it auto-formats when valid XML is detected
- •Watch compression metrics to see bandwidth savings from minification
- •Structure analysis shows complexity: depth, elements, and attributes
- •Download formatted XML with appropriate filename (formatted.xml or minified.xml)

Most users beautify with 2-space indentation for configuration file management
When to Use This Tool
Use beautify mode when working with minified or poorly formatted XML that's hard to read. Perfect for debugging SOAP responses, examining configuration files (web.config, pom.xml, AndroidManifest.xml), or reviewing XML data structures during development. Makes nested elements and hierarchies clear and easy to navigate.
Recommended: Development & Debugging
Use minify mode before deploying XML to production environments. Removes all unnecessary whitespace, line breaks, and optionally comments to reduce file size, minimize bandwidth usage, and improve loading times for XML-based APIs, configuration files, or data feeds. Essential for optimizing SOAP services and XML data transmission.
Recommended: Production Deployment
Enable 'Sort attributes alphabetically' when you need consistent XML output for version control systems, generating meaningful diffs, or maintaining standardized configuration files across different environments. Helps teams collaborate effectively on XML-based projects by ensuring attribute order doesn't create false differences in git diffs.
Recommended: Team Collaboration
Use the formatter to validate XML syntax before sending to APIs, saving to files, or deploying configurations. Get detailed error messages from the browser's XML parser that pinpoint exactly where syntax errors occur (unclosed tags, invalid characters, mismatched elements). Prevents runtime errors from malformed XML.
Recommended: Quality Assurance
How It Works
Select 'Beautify' to format XML with proper indentation and line breaks, or 'Minify' to compress XML by removing all whitespace
In beautify mode, choose your preferred indentation (2 spaces, 4 spaces, or tabs)
Configure options: sort attributes alphabetically, preserve comments (beautify only), include XML declaration, use self-closing tags
Type or paste your XML into the input field - it auto-formats on paste when valid XML is detected
Click the format button to process your XML with real-time validation using the browser's DOMParser
View comprehensive statistics: file size changes, line count differences, and structure analysis (elements, attributes, nesting depth)
Copy the formatted XML to clipboard or download as a .xml file with appropriate filename
100% Private
Files never leave your device. All processing happens locally in your browser.

Frequently Asked Questions
What's the difference between beautify and minify?
Beautify adds indentation, line breaks, and spacing to make XML human-readable and easy to navigate. Minify removes all unnecessary whitespace to create the smallest possible file size. Beautified XML is ideal for development and debugging, while minified XML is better for production use to reduce bandwidth and improve performance.
Will sorting attributes change my XML data?
No, sorting attributes only changes the order in which attributes appear within elements, not the actual data or values. XML attributes are unordered by specification, so the XML remains functionally identical. This is useful for creating consistent output when committing to version control systems, as it prevents false differences in git diffs caused by attribute reordering.
What indentation should I use?
2 spaces is the most common choice for XML files and follows W3C recommendations. 4 spaces is traditional for some legacy systems. Tabs offer flexibility but can display inconsistently across editors. Choose based on your project's coding standards or team conventions. Most modern XML projects use 2-space indentation.
Should I preserve comments in production?
For development and documentation, preserve comments to maintain context and explanations. For production deployment, disable 'Preserve comments' in minify mode to reduce file size. Comments in XML configuration files can be helpful for developers but add unnecessary bytes in production environments where bandwidth and performance matter.
What are self-closing tags and when should I use them?
Self-closing tags (like <element />) are a compact way to represent empty elements instead of <element></element>. They're part of XML specification and reduce file size slightly. Enable this option for cleaner, more concise XML. Some legacy XML parsers might not support them, but all modern parsers handle self-closing tags correctly.
Is my XML data secure and private?
Yes, all XML processing happens entirely in your browser using JavaScript and native browser APIs (DOMParser, XMLSerializer). Your XML is never sent to any server, uploaded anywhere, or stored remotely. This makes it completely safe to format sensitive configuration files, API credentials, or proprietary XML data.
