What Is an XML Formatter?
An online XML formatter pretty-prints XML with consistent indentation so nested elements, attributes, and namespaces are easier to read. Use it for SOAP envelopes, RSS feeds, sitemap.xml files, and other structured documents before you copy them into an editor or commit them.
This free XML formatter runs in your browser. Paste XML to beautify, minify, validate that it is well-formed, and inspect a collapsible tree view. No sign-up; nothing is uploaded.
Well-Formed vs Valid (DTD / XSD)
Well-formed XML has matching tags, a legal structure, and correct entity escaping. Valid XML also matches a DTD or XSD schema. This tool focuses on well-formed checks and formatting—schema validation is a separate step after the document parses cleanly.
SOAP, RSS, Sitemaps, and Namespaces
Pretty-print preserves the XML declaration (including UTF-8 encoding when present), attributes, self-closing tags, CDATA sections, and namespace prefixes. That makes it useful as a SOAP XML formatter or sitemap checker when you need readable structure without changing meaning.
XML Formatter FAQs
What is an XML formatter?
An XML formatter (or pretty XML formatter) indents nested elements and attributes so SOAP envelopes, RSS feeds, and sitemap.xml files are easier to read. This online tool also checks that the document is well-formed.
Is this the same as XSD or DTD validation?
No. This page checks well-formed XML—matching tags, legal structure, and entity escaping. Validating against an XSD schema or DTD is a separate step after the document parses cleanly.
Does the XML formatter work with SOAP and RSS?
Yes. Paste SOAP envelopes, RSS/Atom feeds, or sitemap.xml documents to pretty-print and inspect them in the collapsible tree view. Namespaces and attributes are preserved.
Can I minify XML as well as pretty-print it?
Yes. Beautify adds indentation (2 or 4 spaces). Minify removes insignificant whitespace between elements while keeping the same structure and XML declaration when present.
Is my XML uploaded to a server?
No. Formatting and well-formed checks run in your browser with the DOM parser. Nothing is sent to LiveTechHacks—free, private, and no sign-up.
Why do I get an XML parsing error?
Common causes include mismatched tags, missing closing tags, unescaped & characters, or a broken XML declaration. The tool highlights the message and, when available, the line and column.
