XML formatter
WEBFree online XML formatter and beautifier that pretty-prints, indents, and minifies XML documents in your browser.
What is the XML formatter tool?
This XML formatter pretty-prints flat or minified XML into a clearly indented, easy-to-read tree — free, with no sign-up, and processed entirely in your browser. Paste a sitemap, an RSS feed, a SOAP payload, a config file or any XML snippet, click Beautify, and the nesting of elements and attributes becomes obvious at a glance. Syntax highlighting helps you follow the structure and spot mismatched tags while you edit, and you can copy the result or download it as an .xml file in one click.
The same tool minifies too: choose Minify to remove comments and the whitespace between tags when you need a compact payload for transmission or storage. Attributes, namespaces and nested elements are handled gracefully in both directions, so your document stays valid after formatting. That round trip is handy when you are debugging an API response one minute and shrinking it back down the next.
XML often carries business data — invoices, orders, exports, integration payloads — which is exactly why this formatter never sends anything to a server. Everything runs client-side on your device, so your documents stay private, and the page keeps working offline once loaded. Whether you just need to open and read an XML file someone sent you, inspect a SOAP response, or prepare a sitemap for review, you get a readable structure in seconds — on desktop or on your phone.
How to use the XML formatter
- Paste or type your XML into the editor.
- Click Beautify to pretty-print the document with clear indentation.
- Or click Minify to strip comments and whitespace between tags.
- Follow the element tree with syntax highlighting and check for mismatched tags.
- Copy the XML or download it as an .xml file.
Frequently asked questions
How do I open and read an XML file?
Open the file in any text editor, copy its contents and paste them here, then click Beautify. The flat markup expands into an indented tree where each element sits on its own line, which makes even large feeds and exports readable without special software.
What's the difference between beautifying and minifying XML?
Beautify pretty-prints the document with indentation and line breaks so humans can read it; minify removes comments and the whitespace between tags so machines can transmit and store it compactly. The data itself is identical either way, and you can convert back and forth freely.
Is my XML uploaded to a server?
No. The formatter processes your XML entirely in your browser on your device — nothing is transmitted or stored anywhere else. Since XML files often contain business data like orders and exports, that local processing is the point.
Does it handle attributes and namespaces?
Yes. Attributes, namespace prefixes and nested elements are preserved exactly, so the formatted document stays valid and semantically identical to the input.
What kinds of XML can I format?
Any well-formed XML: sitemaps, RSS and Atom feeds, SOAP requests and responses, Android and Maven config files, SVG source, office document internals — if it parses as XML, it pretty-prints.
Is the XML formatter free?
Yes, completely free — no account, no watermark and no limit on the size or number of documents you format.
