It checks that your XML is well-formed — meaning every tag is properly closed, elements nest correctly without overlapping, and attribute values are quoted. If a rule is broken, the error is flagged with a line reference. Note that well-formedness is different from validation against a DTD or schema, which checks whether elements appear in a specific required order.

Well-formed XML follows the basic syntax rules: matching tags, proper nesting, quoted attributes, and escaped special characters. Valid XML additionally conforms to a DTD or XML Schema that defines which elements are allowed, in what order, and with what content. This formatter checks well-formedness, which is enough to confirm the document will parse, but it does not perform schema validation.

Yes. SVG graphics, RSS and Atom feeds, and XML sitemaps are all XML-based, so the formatter indents and tidies them just like any other XML document. This is handy for inspecting an SVG's structure before editing it, checking that a sitemap is well-formed before submitting it to search engines, or reading a feed that arrived as a single compressed line.

In XML, the ampersand character has special meaning and must be written as the entity &amp; when you want a literal ampersand. A raw & in text or an attribute value makes the document not well-formed, which the formatter flags. The same applies to < and > inside content, which should be written as &lt; and &gt;. Escaping these characters resolves the error.

Yes. You can format with 2-space or 4-space indentation depending on your preference. Two spaces keeps deeply nested documents from drifting too far to the right, while four spaces can make shallow structures easier to scan. Either way the indentation is applied consistently throughout the document so the nesting levels remain clear from top to bottom.

No. The formatter only adds indentation and line breaks between elements; it preserves all tags, attributes, and text content exactly. The data and structure are identical before and after — only the whitespace layout changes. Be aware that in rare cases where whitespace inside an element is significant to your application, you should confirm the formatted output still meets that requirement.

Yes. All formatting and well-formedness checking happen locally in your browser using JavaScript, so the XML you paste is never sent to a server or stored. This makes the tool safe for configuration files, API responses, and any document containing internal details. Once the page has loaded it also works offline, since no server round-trip is needed to format your content.
