XML Formatter/Validator: Clean Up and Validate XML Data
Format messy XML into clean, indented structure and validate it against proper XML syntax rules. Spot errors instantly.
What It Does
The XML Formatter takes unformatted or minified XML and transforms it into properly indented, readable XML. The validator checks for syntax errors like unclosed tags, mismatched elements, and invalid characters, highlighting the exact location of each problem.
How to Use It
Paste your XML into the editor. Click Format to apply proper indentation and line breaks. The validator runs automatically and highlights any syntax errors with descriptions and line numbers. Copy the formatted output or fix errors inline.
Tips & Tricks
Valid XML requires every opening tag to have a matching closing tag. Attribute values must be quoted. Special characters like ampersands and angle brackets must be escaped in text content. Check encoding declarations for non-ASCII content.
Use Cases
Developers format API response XML for debugging and readability. Configuration managers validate XML config files before deploying changes. Data engineers clean up XML exports from legacy systems for processing.
