XML Formatting Best Practices
Properly formatted XML improves readability and makes it easier to spot structural issues. Use consistent indentation, keep attributes on the same line as the element when short, and always validate your XML before sending it to APIs or configuration files.
FAQ
Does it validate XML?
Yes. The formatter uses the browser's built-in DOMParser which validates XML structure. Any parsing errors are shown clearly in the status line.
Are CDATA sections preserved?
Yes. CDATA sections, comments, and processing instructions are all preserved during formatting.
Can I customize indentation?
Yes. Choose between 2 spaces, 4 spaces, or tab indentation from the options dropdown.
Is my data sent anywhere?
No. All formatting runs 100% in your browser using JavaScript. Your XML never leaves your machine.
