About This Calculator
This XML formatter parses your XML, checks that it is well-formed, and re-prints it with readable indentation.
Well-formed XML requires a single root element, properly closed tags, and correct attribute quoting. If your input has an error, the tool reports it so you can fix it. Choose 2-space, 4-space, or tab indentation to match your team’s style.
All parsing happens in your browser — nothing is uploaded.

Frequently Asked Questions
What does "well-formed" mean?
It means the XML follows the syntax rules: one root element, every tag closed, attributes quoted, and no stray text at the document root.
Can it format HTML too?
Strictly it expects XML rules. For looser, HTML-style documents use the HTML formatter instead.
