XML Formatter / Validator
XML (eXtensible Markup Language) is a standard format for structured data exchange, widely used in web services (SOAP), configuration files, RSS feeds, and enterprise integrations. Proper formatting makes XML documents easier to read and debug.
This tool formats, minifies, and validates XML documents. It detects syntax errors like unclosed tags or invalid nesting, and lets you choose your preferred indentation size for formatted output.
How it works
XML uses a tree structure with opening and closing tags. Every element must be properly nested and closed. Attributes are placed inside opening tags as key="value" pairs.
Use cases
- Formatting SOAP API request and response payloads
- Validating XML configuration files before deployment
- Minifying XML for reduced payload size in data transfers
- Debugging RSS/Atom feed markup issues
