XML Formatter

What is an XML Formatter?

An XML Formatter takes raw XML and turns it into a clean, indented tree so tags and their nesting are easy to read. The Minify mode does the opposite: it strips whitespace between tags to compress the code for transfer or storage. Malformed XML is reported with a clear error instead of failing silently.

Where is it useful?

• Web services: reading API request and response payloads.
• Config files: cleaning up application and build configuration in XML.
• Sharing: reformatting minified XML into readable form for colleagues.
• Debugging: spotting mismatched tags and broken nesting at a glance.

Is my data safe?

Yes. Formatting, validation and minifying all happen locally in your browser; your XML is never sent to any server, so even configuration with sensitive values can be handled safely.

How pretty-printing works

A formatter reads the indentation already present, then rebuilds every level of the tree so child elements line up consistently with their size. Attributes stay on their elements and comments keep their place, turning dense markup into a structure you can read top to bottom.

Formatting is not validating

Pretty output only proves that the document is parseable. A wrong element name or misplaced attribute still formats cleanly — keep a validator for correctness and the formatter for readability. Broken XML surfaces as an error instead of silent output, so fix validation first.
