About JSON Schema Generator
JSON Schema describes the structure a JSON document must follow — field types, which are required, and the shape of arrays/objects. Writing it from scratch is tedious.
This tool infers a schema (draft-07) from your JSON sample automatically: it detects types, marks fields as required, and walks nested objects/arrays.
Use the generated schema to validate future data (see the JSON Schema Validator). Processed in the browser.
FAQ
Is my data sent to a server?
No. JSON Schema Generator runs entirely in your browser using client-side libraries. Your data never leaves your device.
