What is a JSON diff?
A diff highlights structural and textual changes between two documents. For JSON, you typically compare pretty-printed trees or normalized text so key moves and value edits are obvious during code review or incident analysis.
How to use this tool
Paste left and right inputs (JSON or plain text). Scan highlighted regions for drift. Export or copy from the full tool when you need to share findings with your team.
Use cases
API contract reviews, config drift between environments, debugging serialization changes, documenting before/after for changelogs.
