XML Formatter

XML Formatter is a tool that reads any XML document and rewrites it with clean, consistent structure. Paste a minified or messy XML payload - a SOAP envelope, an RSS feed, a Maven pom.xml, an Android layout, a sitemap - and get back readable, properly indented markup, or collapse a formatted document down to a single compact line when you need the smallest possible size.

Here is the online XML formatter on a small payload. Paste <note><to>Ana</to><body>Hi &amp; bye</body></note>, keep Beautify and 2 spaces, and press Format. The output puts <to> and <body> on their own lines, indented two spaces inside <note>, and the header reads "3 elements · 4 lines · 57 bytes". Switch to Minify and press it again, and the same document is back on one line at 50 bytes. The &amp; stays exactly as written. This XML formatter is free, no signup, and there is no upload step.

Raw XML from APIs, build tools, and exports often arrives on one enormous line, or with mixed tabs and spaces that make it impossible to scan. Beautifying it reveals the element hierarchy so you can find the node you need, spot a missing tag, or diff two versions. Minifying does the reverse - stripping the whitespace between tags to shrink a config file or a request body without changing its meaning. This tool does both, and checks the tag structure along the way so unclosed and mismatched tags are caught before they reach your parser.

Everything runs 100% in your browser using a dependency-free parser - no DOMParser, no server round trip. XML documents frequently carry configuration, integration payloads, or internal identifiers, so nothing you paste is uploaded or stored. Comments, CDATA sections, the XML declaration, and your original attribute order are all preserved, and the tool keeps working offline once the page has loaded.

Formatting preserves what carries meaning and normalises what does not. Attribute order is kept, because although XML treats it as insignificant, diff tools and reviewers do not. CDATA sections and comments survive untouched. Whitespace is where you need to be careful. In XML a space between text and a child element is part of the document, not layout, and this formatter does not special-case it: leading and trailing spaces in every text node are trimmed, and mixed content such as <p>Hello <b>world</b> again</p> is split so each piece sits on its own line, while Minify joins the pieces with no spaces at all. Leave prose-style markup like that unformatted.
