About JSON Diff

JSON Diff compares two JSON objects key by key and highlights the differences. Unlike plain text diff, it understands the JSON structure and shows exactly which keys were added, removed, or changed. This is especially useful for comparing API responses, configuration files, and database records. All comparison happens locally in your browser.
