Difference
The XML Diff tool compares two documents and highlights exactly what changed — added elements, removed nodes and modified attributes or values. Paste the original and the revised version, run the comparison, and the differences are laid out clearly rather than leaving you to scan two long files side by side. It is used to review configuration changes before a deploy, confirm what a transformation actually altered, and check the difference between two API responses. Formatting-only noise is ignored so only genuine structural changes show, and both documents are compared entirely in your browser.
