HTML Formatter & Beautifier

Compact or single-line XML, common in SOAP responses, RSS feeds, and config exports, is nearly impossible to read without proper indentation. This XML formatter parses your document and rewrites it with consistent indentation and correct tag nesting, making the hierarchy immediately clear. It's used by developers debugging web service responses, integrators inspecting SOAP payloads, and anyone maintaining XML-based configuration files who needs to review structure quickly. The formatter also flags malformed XML, such as unclosed tags, so you catch structural problems while beautifying. Because everything runs client-side in your browser, your XML content is never uploaded to a server, and there's no signup required. Paste your XML below to see it beautifully indented in an instant.

Frequently asked questions
What does an XML formatter do?
It rewrites compact or single-line XML with consistent indentation and line breaks so the tag hierarchy is easy to read, without changing the actual content.
Does formatting validate that my XML is well-formed?
Yes, the formatter flags issues like unclosed tags or mismatched elements while it processes your document.
Can it format XML with namespaces and attributes?
Yes, namespaces, attributes, and CDATA sections are preserved exactly as written, with only whitespace and indentation adjusted.
Is my XML data uploaded to a server?
No, formatting happens entirely in your browser using client-side JavaScript, so your document is never sent anywhere.
Can this tool also minify XML?
Yes, you can toggle to a minified view of the same document to strip out whitespace for production use.
What indentation style does the formatter use?
You can choose your preferred indent width, typically 2 or 4 spaces, to match your project's conventions.
Does it handle very large XML files?
Yes, since processing is entirely local, typical multi-megabyte XML files format almost instantly.
