When to Format or Minify XML

Pretty-printing XML makes it easier to read and debug — essential when working with SOAP responses, Maven POM files, Spring configuration, or RSS feeds. Minifying removes all whitespace to reduce file size, which is useful for SOAP requests, embedded XML in databases, or reducing network payload in API integrations.

Is my data safe?
All formatting happens locally in your browser using JavaScript. Your XML is never uploaded to any server. It's safe to use with sensitive or proprietary data.
