What is JSON Diff?
JSON Diff is a side-by-side visual comparison tool that allows you to compare two JSON objects and find structural, key, or value differences. It highlights additions, deletions, and updates in easy-to-read, color-coded layouts, allowing developers to debug API responses, database differences, or config overrides.
How to use JSON Diff?
1
Paste your primary JSON into the left panel (Source).
2
Paste the secondary JSON into the right panel (Target).
3
Click "Compare" to run the diff comparison.
4
Scroll through the highlighted lines where red indicates deletions/changes, green indicates additions, and yellow indicates updated values.
