XML Formatter

An XML formatter is a specialized data utility that cleans up, indents, and organizes raw XML documents into a human-readable structure. XML (eXtensible Markup Language) is widely used for configuration files, data exchange between older systems, and Android app development. Because XML can become deeply nested and complex, "Minified" or poorly formatted XML is almost impossible to debug. Our formatter applies consistent hierarchical indentation and attribute alignment, making it easy to see the relationship between parent and child nodes. Whether you are working with RSS feeds, sitemaps, or SOAP API responses, this tool ensures your data is clear and professional.

How to Use XML Formatter Step by Step

1. Paste your "XML Code" — input the raw or messy XML string.
2. Select "Indentation Level" — choose between 2 spaces or 4 spaces.
3. Toggle "Attribute Wrapping" — choose whether to put each attribute on its own line for readability.
4. Click "Format XML" — the tool will parse the tags and apply consistent nesting.
5. Review the "Visual Tree" — use the formatted output to understand the data structure.
6. Copy to Clipboard — use the one-click button to save the beautified XML.

XML Formatter Formula Explained

The formatter uses a "Non-Destructive Parser" that builds an internal representation of your XML tags. It identifies "Text Nodes" (the content) vs "Element Nodes" (the tags). It then walks through this tree and re-writes it. For every level of depth it encounters, it prepends the appropriate number of spaces to the line. It also handles "Self-Closing" tags (e.g., `<item />`) and ensures that comments are correctly aligned with the code they describe, resulting in a perfectly balanced and readable document.
