XML Formatter

XML — eXtensible Markup Language — is a plain-text format for representing structured, hierarchical data. It looks similar to HTML but is designed to describe data rather than presentation. Every piece of information sits inside a named tag with optional attributes, which makes an XML document self-descriptive and language-independent.

XML has been a workhorse of the software industry for decades. It still powers RSS feeds, SOAP web services, SVG graphics, sitemaps, Android layouts, Microsoft Office (docx / xlsx), Java Spring configuration, Maven builds, financial messaging, and countless enterprise data exchanges.

Real-world XML is usually minified for network transport or produced by machines without any indentation at all. Reading, debugging, or diffing such a document is painful. Formatting adds consistent indentation and line breaks so you can quickly scan the tree, spot a missing attribute, or share a readable payload with a teammate. Combined with validation and a tree view, you can locate any node in seconds — instead of scrolling through a single-line wall of text.

• Web development — inspecting SVG, RSS, sitemaps, and legacy XHTML.
• APIs — debugging SOAP envelopes, XML-RPC and REST XML payloads.
• Configuration files — reading Maven, Spring, Log4j, Tomcat, and NuGet configs.
• Mobile apps — formatting Android layout, drawable, and manifest files.
• Enterprise software — banking, healthcare (HL7 / CDA), and government data exchange.
• Data exchange — cleaning up exports before importing into another system.
• System integration — validating message templates and inspecting webhook payloads.

Everything runs in your browser. There is no server, no upload, no third-party API. Your XML never leaves the tab — so this tool is safe for internal configs, API responses containing customer data, financial messages, or any confidential payload.
