What is XML Formatter?
Got messy XML that's impossible to read? This tool fixes that. It takes your XML and makes it readable – proper indentation, line breaks, everything organized. Whether you're debugging API responses, checking config files, or just trying to understand what your XML actually says, this makes it readable.
XML is widely used for data storage and configuration. The formatter follows XML standards, so your formatted XML is always valid and standards-compliant.
Best part? Everything happens instantly in your browser. No server uploads, no data storage – just paste, format, and copy. Your XML stays private.
What Makes This Tool Different
Pretty Print Instantly
Paste minified XML and get perfectly formatted output in milliseconds. We use consistent indentation so nested elements are easy to read.
Syntax Validation
While we format, we also validate your XML. If something's broken, we'll show you exactly where so you can fix it fast.
Minify Option
Need compact XML for production? One click minifies everything, removing all whitespace while keeping it valid. Perfect for API requests or config files.
File Upload Support
Got a big file? Just upload it. Works with .xml files. No need to copy-paste – just drag and drop or click upload.
Copy & Download
One click to copy, or download it as a .xml file. Perfect for saving formatted versions or sharing with your team.
Syntax Highlighting
Our editor provides beautiful syntax highlighting. Tags, attributes, and values are color-coded for easy reading.
How It Works
Paste or Upload XML
Paste your XML code into the left editor, or click "Upload" to load a file. You can also click "Sample" to see example XML. The tool accepts any valid XML structure – elements, attributes, nested tags, you name it.
Automatic Formatting
As soon as you paste, the formatter processes your XML and displays the beautifully formatted version on the right. Nested elements get proper indentation, attributes are aligned, and everything is organized perfectly.
Copy or Download
Click "Copy" to copy the formatted XML to your clipboard, or "Download" to save it as a file. Need minified XML instead? Click "Minify" to compress it. All processing happens instantly in your browser.
When You'd Actually Use This
API Development
Format XML responses from APIs to understand the structure, debug issues, or document endpoints. Works great with SOAP APIs or REST APIs that return XML.
Config File Review
Reviewing XML configuration files? Format them first to see the structure clearly. Makes it easier to spot errors, understand settings, or compare different configurations.
Learning XML
New to XML? Formatting helps you understand the syntax. See how elements nest, how attributes work, and how data structures are organized. Much easier than reading minified code.
Debugging
Trying to find a bug in your XML? Formatting reveals the structure, making it easier to spot missing closing tags, incorrect nesting, or attribute issues. The validation feature catches syntax errors instantly.
Common Questions
Is my XML data stored?
No. All formatting happens in your browser using JavaScript. Your XML never leaves your computer.
What XML formats are supported?
We support all valid XML according to the W3C XML specification. Elements, attributes, namespaces, CDATA sections – everything standard XML supports.
Can I format invalid XML?
We'll try to format it, but if there are syntax errors, the output might not be perfect. Fix syntax errors first for best results. Use our XML Validator to check first.
What indentation does it use?
We use consistent spacing for indentation, making nested structures easy to read. The exact style follows common XML formatting conventions.
How big can my file be?
Since processing happens in your browser, performance depends on your device. Small files format instantly. Very large files (several MB) might take a few seconds, but they'll still work.
Can I customize the formatting?
Currently, we use standard formatting conventions. If you need specific formatting options, consider using command-line tools like XMLStarlet for advanced customization.
