Frequently Asked Questions
What does an XML formatter do?
It re-indents XML with consistent nesting and line breaks so the structure is readable, and checks that tags are properly opened and closed.
Is my XML uploaded anywhere?
No. The formatter works entirely in your browser. Nothing is sent to a server, stored, or logged.
Why won't my XML format correctly?
Usually because a tag is not closed, attributes are unquoted, or there are multiple root elements. Valid XML needs a single root and properly nested, closed tags.
What is the difference between XML and HTML?
XML is a strict, general-purpose format for storing and transporting data with custom tags. HTML is a fixed set of tags for displaying web pages and is more forgiving of errors.
