Copy the formatted XML for use in configuration files, API payloads or documentation.

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.
