XML Formatter & Validator
Format messy or minified XML into clean, indented markup, or compress it down to a single line. Choose 2-space, 4-space, or tab indentation. A live well-formedness check uses the browser’s native parser to flag mismatched tags and malformed syntax, showing the parser error inline. Perfect for debugging API responses, config files, SVG, RSS, and sitemaps. Nothing is uploaded — all processing is client-side.

Frequently Asked Questions
QDoes it validate my XML?
Yes. It runs your XML through the browser’s native parser and flags any well-formedness error (mismatched or unclosed tags, invalid characters) with the parser message.
QCan it minify as well as beautify?
Yes. Use Minify to strip whitespace between tags into a single compact line, or Beautify to re-indent with your chosen spacing.
QIs my XML sent to a server?
No. Formatting and validation happen entirely in your browser; your data never leaves your device.
