FAQ
- What is the difference between formatting, minifying, and validating XML?
- Formatting adds indentation for readability, minifying removes whitespace for compact output, and validation checks syntax correctness. These operations do not change the underlying data model.
- Does this tool send my XML to a server?
- No, all processing happens in your browser. Your XML is never transmitted to any server by this tool.
- Does it support XML namespaces and CDATA sections?
- Yes, the formatter uses the browser's native XML parser which supports namespaces, CDATA, and standard XML 1.0 features. Output may normalize some formatting details.
- Why does my formatted XML look different from the input?
- The parser normalizes whitespace between tags and may reorder attributes. The logical structure and content remain the same; only presentation changes.
