XML Formatter
Paste XML to prettify, minify, or validate it. All processing happens in your browser — nothing is sent to any server.
Frequently Asked Questions
How do I format or beautify XML online?
Paste your XML and the formatter re-indents it with consistent spacing and line breaks so the structure is easy to read. You can choose the indentation size, then copy the result.
What does minifying XML do?
Minifying removes unnecessary whitespace and line breaks between elements, producing compact XML with a smaller file size. The data stays identical — only the formatting changes.
Why is my XML invalid?
Common problems are unclosed or mismatched tags, missing quotes around attribute values, or more than one root element. The validator points to where parsing fails so you can fix it.
Is my XML uploaded anywhere?
No. The XML is parsed and formatted entirely in your browser, so configuration files and data feeds stay private and are never sent to a server.
