About JSON Diff

Updated Jan 2025

The JSON Diff tool compares two JSON inputs and visually highlights additions, deletions, and modifications. It normalizes formatting before comparing so that whitespace differences are ignored. Perfect for reviewing API response changes, comparing configuration versions, or debugging data transformation pipelines.
