XML Viewer with Validation

About This Tool

This XML Viewer with Validation combines processing with automatic syntax validation, ensuring your XML data is structurally correct before transformation. When you paste data and click the action button, the tool first attempts to parse the input according to the strict specification. If the data contains syntax errors — missing commas, unmatched brackets, invalid escape sequences, or other structural issues — the tool reports the specific error rather than producing corrupted output. This validation-first approach prevents a common development workflow problem: processing invalid data and then spending time debugging the output rather than the input. In production environments, validating data before processing is a best practice that prevents cascading errors, data corruption, and difficult-to-diagnose bugs.

What is XML Viewer?

An XML viewer provides validation and a formatted structural view of XML documents in one tool. It validates the document for well-formedness, reports element count and attribute count, and displays the formatted XML with proper indentation to reveal the complete element hierarchy. This dual-purpose tool is ideal for quickly inspecting XML from APIs, feeds, and configuration files without switching between a validator and a formatter. Whether you are debugging a failing SOAP service, exploring an unknown XML schema, or reviewing a configuration file, the XML viewer gives you immediate insight into the document's structure and validity.

How to Use This Tool

1. Paste your XML.
2. Click Inspect XML.
3. See validation results and element statistics.
4. View the formatted XML below the report.
