- What is XML formatting?
- XML formatting adds consistent indentation and line breaks to XML documents, making the element hierarchy and nesting structure immediately visible without changing any data.
- Can I format invalid XML?
- The formatter uses a structural approach that handles most XML, but documents with significant syntax errors may produce unexpected output. Use the XML Validator to check validity first.
About This Tool
Configuration files are at the heart of modern software development — from package.json and tsconfig.json to VS Code settings and cloud infrastructure templates. This XML Formatter for Config Files is tailored for processing XML configuration files with the precision and care they require. Configuration files often contain comments (in formats that support them), version-specific settings, and carefully structured hierarchies that must be preserved during formatting. The tool processes these files while maintaining all data integrity, ensuring that indentation reveals the logical structure of configuration sections, nested settings, and conditional values. Whether you are cleaning up auto-generated configuration, merging settings from multiple sources, or preparing config files for documentation, this tool handles the task reliably.
What is XML Formatter?
An XML formatter takes raw or poorly indented XML and produces a clean, human-readable version with consistent 2-space indentation for each nesting level. XML (Extensible Markup Language) is widely used for configuration files, data exchange between systems, SOAP web services, RSS/Atom feeds, and document formats like Office Open XML and SVG. Minified or machine-generated XML is nearly impossible to read without formatting. This tool parses the XML structure, identifies elements and their nesting depth, and outputs a properly indented document that makes the hierarchy immediately clear. It also offers minification to compress XML by removing all unnecessary whitespace.
How to Use This Tool
- Paste your XML into the input area.
