Making XML readable again
XML has a habit of arriving as one unbroken line — exported from a system, pulled from an API, or minified for transport. Formatting it restores the indentation and nesting so the document's shape becomes obvious and you can find the element you're after without scrolling sideways forever.
Validate before you ship
A misplaced tag or an unclosed element can quietly break whatever consumes your XML. The built-in validation checks that the document is well-formed and points you at the problem if it isn't, so you catch the slip here rather than in a failing integration later. Need it compact again? Minify it in one click. Nothing is uploaded — it's all processed locally.
Frequently Asked Questions
What is the difference between XML and JSON?
Both are data formats. XML uses tags like HTML and supports attributes, comments, and namespaces — making it suitable for complex data and document structures. JSON is lighter and simpler, making it preferred for most modern web APIs. XML is still dominant in enterprise systems, banking, healthcare (HL7), and legacy integrations.
Is my XML data private when I use this tool?
Yes. The formatter runs entirely in your browser. No XML content is uploaded to any server. Your data is processed locally and stays private.
What is XML minification used for?
Minifying XML removes all whitespace, indentation, and comments to reduce file size. This is useful when transmitting XML over networks or storing large volumes of XML data where every byte matters.
