How to use the XML Formatter
Paste your input
Drop the snippet, token or document into the editor. Invalid characters are highlighted as soon as parsing fails.
Choose how to process it
Select formatting, validation or conversion options. Results are calculated as you type, with no submission step.
Copy or download
Use the copy button for a clean result, or download it when the output is large.
What XML Formatter is for
Reformat XML with consistent indentation, collapse empty tags and spot mismatched elements. Handy before diffing two configuration files.
The XML Formatter is part of the Developer collection on ToolFlow. It is designed for one concrete job: indent and clean up XML markup. Everything runs client-side, so you can use it with sensitive material without creating a copy on someone else's server.
Common use cases
- Pretty-print a SOAP payload
- Check tag nesting
- Shrink XML for transport
Good to know
- No account is required, and there is no usage limit on the browser tool.
- Processing happens locally. Files are read from disk and the result is written back to your downloads folder.
- Results are reproducible: the same input and options produce the same output, with no hidden server round-trip.
- If the tool needs a live data source, the page states it explicitly instead of silently failing.
