JSON Schema

What is a JSON Schema Validator?

This tool verifies that your JSON matches a defined schema. It’s useful for ensuring API responses follow the expected structure.

Example:

JSON:
{ "id": 101, "active": true }

Schema:
{
  "type": "object",
  "properties": {
    "id": { "type": "number" },
    "active": { "type": "boolean" }
  },
  "required": ["id", "active"]
}
