What is an XML Formatter?
An XML formatter takes raw, unindented XML and restructures it into clean, human-readable code with proper indentation and line breaks. Developers use it every day when debugging API responses, reading config files, or working with SOAP web services and schema-heavy integrations.
XML Formatter at xmlformatter.in formats your XML in one click. You can paste text, load a file, or import XML from a URL, then format and validate instantly. The formatter runs in your browser, so data processing is private and direct without forcing any account or setup workflow.
- Formatting SOAP and REST API responses
- Beautifying AndroidManifest.xml and Maven pom.xml files
- Reading RSS, Atom, WSDL, and XSD documents quickly
- Validating XML before production deployment
How to Use XML Formatter
- Paste your XML in the left panel or upload an XML file.
- Choose indentation: 2 spaces, 4 spaces, or Tab.
- Click Format XML for pretty output, or Minify for compact output.
- Copy the result or download as an XML file.
Tip: validation runs before format output. If XML is invalid, the page shows a clear parser error.
