About
ToDiagram
ToDiagram is a data editor that turns JSON, YAML, CSV, and XML into interactive diagrams. You can explore, search, and edit data visually — every change in the diagram updates the code, and every change in the code updates the diagram.
It’s built for developers, analysts, and teams who work with structured data daily. Large files open smoothly, schemas highlight errors directly on the diagram, and you can generate types for TypeScript, Go, Rust, and more.
Beyond data, ToDiagram lets you create your own flowcharts, architecture diagrams, and system designs using a custom format for nodes and edges. Whether you’re debugging an API payload, exploring a dataset, or sketching out system design, ToDiagram gives you one tool to handle it all.
Available on the web, desktop (PWA), and as a Chrome extension.
