Smart JSON Editor
Smart JSON Editor organizes JSON trees, test data and API requests with transformers, JSON Path and an embedded HTTP server.
Pick for creating structured test fixtures and exploring API responses.
Linked objects and dynamic values can reduce repetitive test-data edits.
Keep in mind: The developer site still marks some Smart Object and private-library features Pro, despite the store description's broad free claim. Verify entitlements and never serve live secrets as test fixtures.
