About Xml Formatter
Free online Xml Formatter tool.
Xml Formatter takes messy, single line XML and rewrites it with consistent indentation, one element per line, so the structure becomes readable at a glance. Paste your markup or load a file, pick an indent style of two or four spaces or tabs, decide whether comments and processing instructions should stay, and the formatted result appears instantly beside a collapsible tree view. Validation highlights mismatched tags and reports the line number of the first error, which saves long debugging sessions. Developers use Xml Formatter when editing configuration files, sitemaps, feeds and API payloads, while testers place two versions side by side to compare changes. The tool is free, needs no account and never sends your data to a remote server.

Frequently Asked Questions
Can Xml Formatter point to the exact line where a tag does not match?
Yes. While formatting, the parser walks every element and closing tag, and the first structural problem it meets is flagged with its line number, column and a short description such as an unclosed tag or an unexpected closing tag. The editor scrolls to that spot and highlights it, so you can fix the mistake, reformat and confirm that the document validates cleanly.
Is Xml Formatter free to use?
Yes. Xml Formatter is completely free with unlimited use — no account, download or payment required.
Is my data uploaded to a server?
No. Xml Formatter runs entirely in your browser. Your inputs are never sent to our servers or stored anywhere.
Does Xml Formatter work on mobile?
Yes. The interface is fully responsive and works in any modern browser on Android, iPhone, tablets and desktops.
