XML Formatter & Minifier
What is XML?
XML (eXtensible Markup Language) is a text-based format for storing and transporting structured data. Unlike HTML, XML has no predefined tags — you define your own to describe any kind of data. It is widely used in configuration files, APIs (SOAP, RSS, Atom), office document formats (DOCX, XLSX), and data exchange between systems. Formatting XML makes it human-readable with proper indentation and line breaks, while minifying strips all unnecessary whitespace to reduce file size for transmission. This tool uses the browser's built-in XML parser, so it validates your XML strictly and reports any syntax errors.
How to Use the XML Formatter
-
Paste your XML into the left panel and click Format to pretty-print it with indentation.
-
Click Minify to remove all unnecessary whitespace and produce a compact single-line output.
-
Choose the indent size (2 spaces, 4 spaces, or a tab character) from the dropdown.
-
If your XML has syntax errors, a red error message appears below the input panel.
-
Click Copy to copy the output, or Example to load a sample XML document.
