JSON to Diagram

JSON2Diagram is a browser-based editor for working with structured data like JSON, CSV, YAML, and XML. It helps developers inspect and refine payloads quickly by combining readable formatting with tools for searching, transforming, and validating content. It’s designed for anyone who regularly debugs APIs, cleans up datasets, or prepares data for downstream systems.
