XML Formatter

XML Formatter delivers exactly what its name promises, format and beautify xml documents, fast and free. Because it belongs to ToolsMonk's developer tools collection, the whole workflow happens on a single page instead of being spread across separate apps or websites.

People reach for it most often when they need making a dense xml response or config readable for debugging, re-indenting xml before committing it to a repository, and inspecting the structure of an xml document. With nothing to install, an unexpected one-off job takes no longer to start than your regular routine.

If you have been searching for xml formatter, xml beautifier, and format xml, this page covers those jobs with a clean interface, instant output, and no paywall in the way.

XML Formatter beautifies minified or messy XML with proper indentation, turning a dense block of tags into a clearly-nested, readable document, essential for debugging XML responses, configs, and feeds.

It's a safe, presentation-only change: indentation and structural whitespace are adjusted, but tags, attributes, content, and structure are untouched, so the formatted XML is equivalent to the original. Because whitespace between elements is generally insignificant in XML, this doesn't alter meaning.

Beyond readability, formatting is a practical debugging aid, once the hierarchy is laid out with indentation, a tag that closes in the wrong place or nests incorrectly becomes visually obvious. For strict confirmation that a document is well-formed, pair it with an XML validator.

One nuance: whitespace inside element text content can be significant depending on the schema, so review the result if your data relies on exact text spacing. Everything runs in your browser, so your XML stays private. Pair it with the JSON Formatter and other ToolsMonk developer tools.
