XML Formatter
Free online XML Formatter and viewer
Result
This tool takes minified, single-line, or inconsistently indented XML and reformats it with proper nesting and line breaks so it's actually readable. Formatting happens client-side in your browser, so nothing you paste gets uploaded anywhere.
A single cramped line like this:
<root><item id="1">Text</item></root>
→
<root>
<item id="1">Text</item>
</root>
Does formatting change the XML content?
No, only whitespace, indentation, and line breaks change. Element names, attributes, and text content stay exactly as you entered them.
Is my XML uploaded to a server?
No. Formatting runs entirely in your browser using JavaScript, so your data never leaves your device.
Can this fix invalid XML?
It formats well-formed XML. If yours has a structural error, like an unclosed tag, you'll need to fix that first; a formatter can't guess what you meant.
What's the difference between this and the XML viewer?
The formatter gives you back reformatted text you can copy elsewhere. The viewer renders XML as an interactive, collapsible tree for browsing on-screen.
