ماذا تفعل JSON to TypeScript؟
JSON to TypeScript يتيح تحويل البيانات أو الملفات مباشرة في المتصفح مع شرح واضح للنتيجة والحدود. القدرات المتحقق منها: Nested type inference, Interfaces, Type aliases, Stable local output.
Inference is a starting point, not a schema
Use the generated declarations to bootstrap code from a representative payload. Use OpenAPI, JSON Schema, or a hand-maintained domain model when optionality, validation constraints, and unions must be authoritative.
كيف تستخدمها؟
- Paste a representative JSON object or array into Input.
- Choose Interfaces or Type aliases and select Convert.
- Review nested declarations and manually add optional properties or unions that the sample cannot prove.
مثال فعلي للإدخال والإخراج
Infer a nested object shape
الإدخال
{"id":42,"owner":{"name":"Ada"}}الإخراج
interface Root {
id: number;
owner: Owner;
}
interface Owner {
name: string;
}
type Payload = Root;The generator names nested declarations from property names and infers primitive types from the supplied values.
أخطاء شائعة وطرق الإصلاح
| العرض | السبب المحتمل | الإصلاح |
|---|---|---|
| A field that is sometimes absent is generated as required. | The sample contains only one observed object shape. | Add representative records, then review and mark genuinely optional properties with ?. |
| An array receives the wrong item type. | Inference uses the first array item and cannot discover every production variant. | Replace the inferred item type with a reviewed union or a schema-derived type. |
Important behavior of JSON → TypeScript
حدّ محدد لهذه الأداة: Inference reflects the sample only; optional fields and unions require real schema knowledge.

JSON → TypeScript — FAQ
Does the JSON → TypeScript 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 JSON → TypeScript 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 JSON → TypeScript produce?
It produces TypeScript interfaces or type aliases with nested declarations. Copy and download controls appear when the output format supports them.
What limitation should I know?
Inference reflects the sample only; optional fields and unions require real schema knowledge.
ما الذي تغيّر؟
تحديث جوهري: JSON → TypeScript: Added Nested type inference, Interfaces, Type aliases, Stable local output, responsive controls, explicit runtime disclosure, and task-specific examples and limitations.
