Frequently asked questions
Does this validate whether my XML is well-formed?
The formatter focuses on layout rather than full schema validation, so always double-check that tags are properly closed and nested if you need strictly valid XML.
Will formatting change the data in my XML?
No. Only whitespace between tags is adjusted; element names, attributes and text content are left unchanged.
Is my XML uploaded anywhere?
No. Formatting happens locally in your browser.
