What does the XML formatter do?

The XML formatter parses raw or minified XML and outputs it with consistent indentation and line breaks, making it readable. It also validates your XML and reports any syntax errors such as unclosed tags, missing declarations, or invalid characters.

Is my XML data sent to a server?

No. All formatting and validation is performed locally in your browser using JavaScript. Your XML content is never transmitted to any server, making the tool safe for formatting configuration files, API responses, or any sensitive XML data.

Q: What is the difference between XML and JSON?

XML uses nested tags with opening and closing elements and supports attributes, making it verbose but very flexible and widely used in enterprise systems, SOAP APIs, and document formats. JSON uses key-value pairs and arrays, is more compact, and has become the dominant format for modern REST APIs.
