XML Formatter
Format or minify XML with one click. Auto-indents for readability, validates syntax in real time and highlights errors at the exact position.
About This Tool
XML (Extensible Markup Language) remains widely used in enterprise systems, SOAP APIs, configuration files, RSS feeds and SVG graphics. Minified or machine-generated XML can be extremely difficult to read and debug. QuickKit's XML Formatter auto-indents your XML with consistent indentation to reveal its structure at a glance, validates the syntax in real time, and can also minify XML to reduce payload size. All processing uses the browser's built-in DOMParser — nothing is uploaded to any server.
Features
- ✓One-click Format — Auto-indents XML with 2-space indentation for immediate readability, correctly handling nested elements, attributes and self-closing tags.
- ✓Minify — Removes all unnecessary whitespace and line breaks to produce the most compact XML representation, ideal for network payloads.
- ✓Real-time Validation — Uses the browser's DOMParser to detect XML syntax errors and shows the error message so you can locate and fix the issue quickly.
- ✓Privacy-safe — All processing runs locally in your browser. No XML content is ever sent to a server — safe for sensitive configuration data.
FAQ
- What types of XML can this format?
- Any well-formed XML, including SOAP envelopes, RSS feeds, Maven POM files, SVG source, Android manifests, Spring configuration files and general-purpose data XML.
- Why does it show a parse error?
- XML is strict — all tags must be properly closed, attributes must be quoted, and special characters like <, >, & must use entity encoding (<, >, &). The error message from the parser usually indicates the line and character position of the problem.
- Does it preserve XML comments and processing instructions?
- Yes. Comments (<!-- -->) and processing instructions (<? ?>) are preserved in the formatted output.
