What happens if my XML isn't well-formed?

You'll see a clear error message instead of a formatted result.

Is my XML data uploaded anywhere?

No — formatting happens entirely in your browser.

Does formatting validate against a schema (XSD/DTD)?

No — it only checks that the XML is well-formed, not that it matches a specific schema.

Does this preserve CDATA sections and comments?

Yes — CDATA sections and comments are treated as self-contained units and preserved as-is.

Does formatting change the actual data?

No — only whitespace between tags changes; element names, attributes and text content remain the same.

Does this work on very large XML documents?

Yes, limited only by your browser's available memory.

What Is an XML Formatter?

An XML formatter takes minified or inconsistently indented XML markup and rewrites it with clean, nested indentation, making the document's element hierarchy easy to follow at a glance.

It's particularly useful for XML returned by APIs, RSS feeds, or SOAP services, which is often minified for transport and hard to read without reformatting first.
