About the XML Formatter

What people use it for
- Reading a minified sitemap or feed.
- Checking a SOAP envelope for structure errors.
- Tidying an export before committing it.
Frequently asked questions
Is the XML Formatter free, or is there a paid tier?
Free, unlimited, and no email address required. You can use it a hundred times a day and nothing changes.
Is the XML Formatter safe to use with private information?
No. The XML Formatter runs entirely in your browser using JavaScript. Because the work happens locally, the page also keeps working if your connection drops, and closing the tab is all it takes to discard everything.
What do people use the XML Formatter for most?
The jobs it is built for: reading a minified sitemap or feed. Checking a SOAP envelope for structure errors. Tidying an export before committing it. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Can I use the XML Formatter on mobile?
Yes. The page is responsive and the page works in Chrome, Safari, Firefox, Edge and Samsung Internet on both Android and iOS. There is no app to install and nothing to sign into.
