XML Formatter Online
Paste any well-formed XML - an API response, a config file, an SVG, an RSS feed - and the tool pretty-prints it with consistent indentation. Formatting runs entirely in your browser using the built-in DOMParser; nothing is uploaded to any server.
Key features
- Formats and re-indents raw or minified XML in the browser via DOMParser, with the tidy result shown in the output pane ready to copy.
- Two in-browser text areas - an input pane for pasting your raw or minified XML and a read-only output pane for the formatted result.
- One-click copy sends the formatted output straight to your clipboard.
- Multi-level nested structures are indented two spaces per level.
What the formatter handles
The formatter handles XML declarations, self-closing empty elements (rendered as <tag />), and single-text-child elements kept on one line so the output stays readable. Text, CDATA, comments, and processing instructions are preserved as the markup is re-indented.
Your XML stays in the browser
Formatting runs entirely client-side with the built-in DOMParser, so the XML never leaves your device and no file is uploaded to any server.

Frequently Asked Questions
What does XML Formatter Online do?
Pretty-print a xml block with consistent indentation.
When should I reach for xml formatter online?
Reach for it whenever raw or minified XML is too dense to read: paste the markup in and DOMParser re-indents every nested tag with two-space steps, keeps the XML declaration, attributes, comments, and CDATA intact, and hands you tidy output you can copy straight from the result pane. A malformed document returns an inline parse message instead of silently reshaping bad markup.
What complementary tools work well alongside xml formatter online?
This page is built for one job: re-indenting a raw or minified XML document with DOMParser and handing you tidy, two-space output you can copy straight from the result pane. Once your markup is readable here, reach for the sibling developer-tools when you need a different format - a JSON or CSS pretty-printer for those payloads - since this formatter stays focused on XML tags, attributes, comments, and CDATA rather than minifying or schema-validating them.
