How to Validate JSON Schema with ToDiagram?

ToDiagram visually checks your JSON data against a provided JSON Schema and highlights any fields that don’t match the expected structure or types. When a mismatch is found—like using a string instead of a number—the corresponding node is marked in red directly on the diagram, making it easy to spot and fix structural errors without digging through raw text or console logs.

Yes, ToDiagram supports JSON Schema validation not only for JSON but also for YAML, CSV, and XML. These formats are automatically converted to a compatible structure under the hood, allowing you to apply your JSON Schema and visually highlight validation issues in red on the diagram—regardless of the original data format.
