What is XML Formatter?

Format, validate and minify XML directly in your browser. The tool makes compact XML easier to read and identifies invalid markup before you copy or download it.

Format XML

Paste XML and format it with indentation so nested elements are easier to inspect. Formatting changes whitespace, not the underlying element structure.

Validate XML

XML must have properly nested elements, matching opening and closing tags, quoted attribute values and a single valid document structure.

Minify XML

Minifying removes unnecessary whitespace between tags. It can reduce text size, but it does not compress the file with a binary compression algorithm.

Privacy

Formatting and validation happen in your browser; pasted XML is not intentionally uploaded to ToolViso for processing.
