XML Formatter
CodeFormat and minify XML with validation
Paste single-line or minified XML from a SOAP payload or a config file and get it reformatted with proper indentation for debugging, or run it in reverse to strip whitespace and comments before embedding it compactly somewhere else. Malformed XML gets a validation error pointing at roughly where the nesting or closing tags went wrong, which is a faster way to spot a mismatched tag than scanning a wall of unformatted markup by eye. CDATA sections and comments are preserved exactly as written rather than reformatted or stripped during formatting, and empty element pairs get collapsed to self-closing tags for cleaner output. This checks well-formedness only; it doesn't validate against an XSD or DTD schema, so a well-formed document with the wrong structure for its intended schema will still pass here.
How to use XML Formatter
- 1.Paste minified or single-line XML to get properly indented, readable output for debugging a SOAP response or config file.
- 2.Minify a formatted XML document to strip whitespace before embedding it in a payload or reducing file size.
- 3.Paste malformed XML to see a validation error pointing at the unclosed tag or mismatched element causing the parse failure.
