The JSON Diff tool compares two JSON objects side-by-side and highlights their differences with clear visual indicators for additions, deletions, and modifications. Essential for developers reviewing API changes, configuration updates, or data migrations, it handles complex nested structures and provides precise diff reporting that's easy to understand at a glance. Whether you're tracking changes between versions or verifying data transformations, the diff tool reveals exactly what changed and where.
You can paste JSON directly into both panels, upload files, or mix input methods to compare documents from different sources. Because comparison runs client-side, your data stays private and results appear instantly without server delays. The tool pairs naturally with other utilities in the suite — use the validator first to ensure both inputs are well-formed JSON, then diff to spot changes. Perfect for code reviews, data audits, or debugging when you need to understand what differs between two JSON structures. Try comparing similar objects to see how detailed the change detection is.
