JSON Diff Tool

Compare two JSON documents and see exactly what changed. This tool flattens both documents into key-value paths and compares every value, showing additions, removals, and modifications at the path level.

Common use cases: comparing API responses before and after a code change, diffing configuration files, verifying database migrations, and reviewing JSON schema changes.
