About XML Formatter

XML (eXtensible Markup Language) is widely used for configuration files, data exchange, APIs, and document storage. However, XML generated by programs or transmitted over networks is often minified — all on one line with no whitespace — making it nearly impossible to read or debug manually.

This XML Formatter parses your XML in the browser, validates its structure, and outputs a neatly indented version. It supports all standard XML including SOAP, RSS, SVG, Maven POM files, Android manifests, and any custom XML schema.

How to Use

  1. 1 Paste your XML into the Input XML box, or click Upload to load a file (up to 5MB).
  2. 2 Choose Format to beautify with indentation, or Minify to compress to a single line.
  3. 3 Select your preferred indent size (2 or 4 spaces).
  4. 4 Click Format XML. Any syntax errors are reported with the line number.
  5. 5 Copy the output to clipboard or Download it as a .xml file.

Common Use Cases

Debugging API Responses

SOAP services and older REST APIs return XML. Format responses to quickly inspect structure and find the data you need.

Reading Config Files

Maven pom.xml, Spring Boot configs, Android manifests, and web.xml files are easier to review when properly indented.

Minifying for Production

Reduce payload size for XML-based APIs and feeds by stripping whitespace before deployment.

RSS & Atom Feeds

Inspect and debug syndication feeds by formatting raw feed XML to understand the document structure.
