$xml formatter
Pretty-print or minify XML. Uses the browser's DOMParser + XMLSerializer for accuracy, then re-indents the output. Validation errors are surfaced inline.
Frequently asked questions
What does XML Formatter do?
Format XML with namespace-aware indentation. The whole thing runs in your browser tab, so it is ready the moment the page finishes loading.
Is XML Formatter free to use?
Yes. XML Formatter is completely free on ToolMunch — no trial, no premium tier holding back the main feature, and no daily or hourly cap on how many times you can use it.
Do I need to create an account or sign up?
No. There is no account, no email address, and no login. Open XML Formatter, do the job, and take the result — nothing is gated behind a signup form.
Is the code I paste in sent to a server?
No. XML Formatter runs entirely inside your browser tab, so the code you paste stays on your own device. Nothing is uploaded, which means there is no copy of it on a server to worry about.
Does XML Formatter work on Mac, Windows, and phones?
Yes. XML Formatter runs in any modern web browser on Windows, macOS, Linux, Chromebook, Android, and iOS. There is nothing to download or install.
Can I use it as many times as I want?
Yes. There is no queue, no per-hour quota, and no counter that runs out — run XML Formatter as often as the work needs.
