Beautify, minify, and validate XML
XML documents can arrive as one dense line or with inconsistent indentation that hides their structure. Formatting re-indents the nested elements so the hierarchy is clear; minifying strips whitespace for compact storage or transport; validating confirms the tags are properly nested and closed. This tool does all three, turning awkward XML into something you can read and trust.
How to use it
- Paste your XML.
- Choose beautify, minify, or validate.
- Copy the result or read the error if validation fails.
Where it helps
- Reading an XML API response or config that came as one line.
- Checking that every tag is correctly opened and closed.
- Compacting XML before storing or sending it.
Questions people ask
Why does validation fail on an unclosed tag? XML requires every element to be closed and properly nested; a missing closing tag makes the document malformed.
Is my XML uploaded? No — formatting and validation run in your browser.
