XML Formatter

Paste XML — get a clean, indented version plus a syntax check. Runs entirely in your browser, no uploads.

Updated April 2026

What it does

Paste XML, click Format, and get a cleanly indented, 2-space output that’s easy to read and diff. Invalid XML surfaces the parser error inline — much faster than opening an IDE. Minify mode strips whitespace between tags when you need the smallest possible payload.

All parsing uses the browser’s built-in DOMParser, so it runs without dependencies and handles namespaces, CDATA, comments, and self-closing tags correctly. For JSON, use JSON Formatter; for YAML↔JSON conversions, YAML ↔ JSON.

How to use it

  1. Paste XML into the input.
  2. Click Format for indented output, or Minify for a compact version.
  3. Read the error message if the parser flags a problem.
  4. Copy the output when it looks right.
