All formatting happens in your browser — your data never leaves your device.

What is a XML Formatter?

An XML Formatter (pretty-printer) adds proper indentation and line breaks to raw or minified XML, making it human-readable. It also validates well-formedness — checking for matching tags, correct nesting, and proper attribute syntax — and can minify XML to reduce payload size.

How to Use It

  1. 1Paste your XML or upload an .xml file
  2. 2Click 'Format' to prettify with indentation, or 'Minify' to compress
  3. 3Select indentation style: 2 spaces, 4 spaces, or tabs
  4. 4Any syntax errors are highlighted with a description

Example

<root><item id='1'><name>Widget</name><price>99</price></item></root> formatted with 2-space indent becomes a clearly readable 6-line XML block. Minified back to one line for API transmission.

Why Use It

  • Debug API XML responses that arrive as unreadable single-line strings
  • Validate XML files before importing into databases or applications
  • Minify XML config files to reduce bundle size in applications
  • Review XML structure when building or testing SOAP API integrations
