JSON Data Model Generator可以处理什么？
JSON Data Model Generator 用于在浏览器中生成结果，并清楚显示处理结果和限制。 已核对的功能： Ten output targets, Nested type inference, Array element inference, Copyable starter models.
Generated models are a typed starting point
Use output to accelerate scaffolding, then reconcile it with the authoritative schema, nullability rules, naming conventions, and serialization library.
如何使用？
- Paste representative JSON and choose the target language or JSON Schema.
- Enter a root type name and generate the model.
- Review inferred nullability and collection types before copying the starter code.
实际输入输出示例
Infer a TypeScript interface
输入
{"id":1,"name":"Ada","active":true}输出
export interface Root {
id: number;
name: string;
active: boolean;
}Each sample property becomes a field whose type is inferred from its value.
常见错误与修复方法
| 现象 | 可能原因 | 修复方法 |
|---|---|---|
| A field should be optional but is required. | One sample object cannot prove that a property may be absent. | Review the API contract and mark optional fields manually. |
| A numeric type is too broad or too narrow. | JSON has one number syntax and does not declare integer width or precision. | Choose a target type using the real value range and serialization contract. |
Important behavior of Data Model Generator
该工具的实际边界： A sample cannot reveal every optional field, union, integer width, validation rule, or API compatibility constraint.
标准与实现参考
- RFC 8259 — JSON (opens in a new tab)Defines the source data types available to inference.
- JSON Schema 2020-12 (opens in a new tab)Defines the schema vocabulary used by the JSON Schema target.
关于Data Model Generator的常见问题
Does the Data Model Generator upload my input?
No. Processing runs in the current browser tab, and the page does not send tool input to a KitLumi processing endpoint.
What input does the Data Model Generator accept?
It accepts a valid JSON object or array. The workspace checks the input and reports malformed or unsupported values before it produces a result.
What does the Data Model Generator produce?
It produces source declarations for nine languages or a draft JSON Schema. Copy and download controls appear when the output format supports them.
What limitation should I know?
A sample cannot reveal every optional field, union, integer width, validation rule, or API compatibility constraint.
