Free Online XML Formatter and Beautifier
Format, beautify, minify, and validate XML with our free online XML formatter. Paste your XML directly, upload a file, or load a sample to see it in action. Messy, unindented XML becomes clean and readable with proper indentation, while valid XML can also be minified into a single compact line for production use. Completely free, no registration required, and all processing happens securely in your browser.
Key Features
Paste or Upload: Work however you prefer - paste XML text directly into the input box, or upload an existing .xml file from your device.
Format and Minify: Beautify messy XML with proper indentation and line breaks, or minify clean XML down to a single compact line to reduce file size.
Clear Error Messages: If your XML isn't valid, the tool tells you clearly instead of failing silently, so you can find and fix the problem quickly.
Adjustable Indentation: Choose between 2 spaces, 4 spaces, or tabs for your formatted output, depending on your project's style.
Common Use Cases
Debugging Configs: Format a minified or single-line XML configuration file to read and understand its structure.
API Development: Validate and beautify XML responses from APIs or web services while building and testing integrations.
File Size Reduction: Minify XML data files before shipping them to production to reduce transfer size.
How It Works
Paste your XML into the input box, upload a file using the Upload button, or click Load Sample XML to try the tool with example data. Click Format to beautify the XML with proper indentation, or Minify to compress it. If the XML is invalid, an error message explains the issue. Once processed, copy the result or download it as a ready-to-use .xml file.
