About XML Formatter & Minifier
XML Formatter & Minifier formats, compacts, and checks XML so element nesting, attributes, and namespaces are easier to review.
Pretty-printing is a review aid, while minification is useful for compact transport. The tool focuses on syntax; it does not validate the document against an external schema or decide whether an XML payload is acceptable to an application.
How to use this developer tool
- Paste the XML document and choose format or minify.
- Run the operation and inspect the line near any parse error.
- Review namespaces, attributes, and encoding declarations before copying the output to the consuming system.
Privacy and data handling
XML processing is local to the browser and does not intentionally send the document to Dev Tools. Use a redacted sample for private records and credentials.

Frequently asked questions
Can the formatter validate an XSD?
No. It checks the XML syntax. XSD or application validation requires the schema and rules used by the receiving system.
Why did whitespace change the document?
Whitespace can be meaningful in mixed content. Inspect documents that contain text nodes rather than assuming every formatting change is semantic-free.
Does formatting resolve namespaces?
It preserves the XML structure and namespace declarations; it does not verify that the namespace URI matches an application contract.
