What is a Json Diff?
A JSON Diff tool compares two JSON objects or arrays and visually highlights every difference between them — additions, deletions, and modifications. It performs deep recursive comparison on nested structures, making it invaluable for debugging API responses, comparing config files, or reviewing data changes.
How to Use This Tool
- Paste the first JSON object into the left panel.
- Paste the second JSON object into the right panel.
- Differences are highlighted instantly with color coding.
- Green indicates additions, red indicates deletions, and yellow indicates changes.
- Copy or download the diff report for documentation.
