About XML Compare & Diff Checker

How do I compare two XML files?

Using our XML diff tool is simple:

  • Paste or upload your original XML in the left panel
  • Paste or upload the modified XML in the right panel
  • Click the "Compare XML" button
  • View the highlighted differences side by side

What do the colors mean?

The diff results use color coding to indicate changes:

  • Green lines (+) - Lines that were added in the modified XML
  • Red lines (-) - Lines that were removed from the original XML
  • Gray lines - Lines that remain unchanged

How does the comparison work?

The tool first formats both XML documents with consistent indentation, then performs a line-by-line comparison. This approach makes it easy to see exactly where changes occurred.

Can I compare large XML files?

Yes, you can compare XML files up to 10MB each. The comparison runs entirely in your browser, so performance depends on your device.

What if the XML is invalid?

If the XML is invalid, the tool will show an error message above the editor in real-time. You can click "Locate in editor" to jump directly to the error location.

Is my data safe?

Your XML data never leaves your browser. All comparison and processing happens locally on your device.
