XML Viewer & Formatter
Parse, format, and inspect XML documents in a clean tree view. Supports namespaces, attributes, CDATA sections, and deeply nested structures. Ideal for working with SOAP services, RSS feeds, Android manifests, Microsoft Office formats, and any XML-based data exchange. All processing happens entirely in-browser — your data stays private.

What is XML?
XML (eXtensible Markup Language) is a flexible, self-descriptive markup language for storing and transporting data. Unlike HTML, XML has no predefined tags — you define your own elements and structure. XML is the foundation of SOAP web services, Android manifests, Microsoft Office formats (docx, xlsx), RSS feeds, and countless enterprise and financial systems.
Despite JSON's rise, XML remains essential in legacy integrations, financial systems (FIX protocol, SWIFT), and platforms like Salesforce, SAP, and Oracle.
XML Structure Rules
- Every XML document must have exactly one root element
- All elements must be properly nested and closed
- Attribute values must be in quotes:
attr="val" - Tags are case-sensitive:
<Name>≠<name> - Special chars must be escaped:
& < > - Declaration (optional):
<?xml version="1.0"?>
Tips & Tricks
- Collapse deep nodes to navigate large XML documents
- Spot mismatched or unclosed tags with instant validation
- Format adds consistent indentation to minified XML
- Inspect SOAP envelopes from API message logs
- All processing is in-browser — no data is uploaded
Common XML Use Cases
SOAP Services
Inspect SOAP request and response envelopes from enterprise web services.
RSS / Atom
Parse and read RSS and Atom feed structures from content publishers.
