JSON Payload Complexity Score
Score JSON nesting depth and structural complexity to surface hard-to-consume payloads and governance signals. Free JSON complexity analyzer by Graph Tools.
Use this free JSON payload complexity scorer to measure the structural complexity of any JSON document. The tool calculates nesting depth, total field count, array variance, and an overall complexity score that surfaces payloads that are hard to consume, parse, or cache. Useful for API design reviews, backend performance analysis, and governance teams tracking response shape trends across services.
