XML Document Processing
XML documents can be deeply nested with configuration files, SOAP messages, and data exports often spanning hundreds of lines. Proper formatting reveals the hierarchical structure that makes XML powerful.
XML Formatting
Our formatter adds consistent indentation, puts each element on its own line, and preserves XML comments. Visual nesting shows parent-child relationships at a glance. Supports configurable indent size (2 or 4 spaces) and attribute alignment.
Well-formedness Validation
The validator checks matching tags, proper nesting, valid character encoding, and namespace declarations. Syntax errors are highlighted with line numbers and clear descriptions. Essential for SOAP web services, RSS feeds, and configuration files.
XML to JSON/CSV Conversion
Transform XML data into JSON or CSV for use in modern applications. Our converter handles attributes, text nodes, namespaces, and nested elements intelligently. Ideal for consuming legacy XML APIs in JavaScript applications.
Enterprise Use Cases
XML remains important in enterprise systems: SOAP web services, SVG graphics, Office document internals (DOCX, XLSX), Android resources, Maven POMs, and configuration files. Formatting and validation tools help debug and understand these documents.
