XML Formatter & Validator
Format, validate, and beautify XML documents with syntax highlighting. All processing in your browser.
What is an XML Formatter?
An XML formatter (or XML beautifier) takes raw, unformatted XML code and adds proper indentation and line breaks to make it human-readable. It also validates the XML structure, checking for well-formedness such as matching opening and closing tags, proper nesting, and correct attribute syntax. This tool formats and validates XML entirely in your browser.
How to Use
- Paste your XML code into the input area, or upload an XML file.
- Choose your preferred indent size (2 spaces, 4 spaces, or tab).
- Click Format / Beautify to indent and structure your XML.
- Click Validate to check for structural errors.
- Use Minify to remove all whitespace for compact output.
- Copy or download the formatted result.
