JSON to TypeScript: Instant Interfaces

Kisi bhi sample object ya array se JSON ko TypeScript interfaces mein convert karein.

Aapka JSON poori tarah aapke browser mein parse aur convert hota hai, isliye woh aapke device par rehta hai aur server par kuch upload nahi hota.

JSON se TypeScript ke baare mein

Yeh json to typescript converter ek sample JSON object ya array ko seconds mein ready-to-use TypeScript interfaces mein badal deta hai. Ek real API response paste karein aur yeh field types infer karta hai, child objects ko unke apne named interfaces mein nest karta hai, objects ke arrays ko ek shape mein merge karta hai, aur kuch items mein missing keys ko question mark ke saath optional mark karta hai. Yeh frontend aur backend developers, QA engineers aur typed clients wire karne wale har kisi ke liye banaya gaya hai jo json se typescript types hand-write karne ki jagah generate karna chahte hain. Ise ek quick typescript interface generator ki tarah kisi anjaan endpoint ko explore karte waqt use karein, ya apne models ko sample payloads ke saath sync mein rakhne ke liye. Sab kuch locally aapke browser mein chalta hai, isliye aap jo JSON paste karte hain woh aapke device par process hota hai aur server par kuch upload nahi hota.

Features

  • Kisi bhi JSON object ya array se named TypeScript interfaces generate karta hai
  • Nested objects ko PascalCase names ke saath unke apne exported interfaces mein badalta hai
  • Objects ke arrays ko har key cover karne wale ek single interface mein merge karta hai
  • Kuch elements mein missing keys ko question mark ke saath optional mark karta hai
  • Aapki sample values se primitive, array, union aur null types infer karta hai
  • Root interface ko apne model se match karne ke liye rename karne deta hai
  • JSON validate karta hai aur syntax errors ka line aur column pinpoint karta hai
  • Result copy karein ya use .ts file ke roop mein download karein

JSON se TypeScript kaise use karein

  1. Apna JSON object ya array input box mein paste karein.
  2. Root interface name ko apne model se match karne ke liye set karein, ya Root rehne dein.
  3. Output panel mein generate hue TypeScript interfaces review karein.
  4. Result copy karein ya use .ts file ke roop mein download karein.

Example

Input

{ "id": 1, "name": "Ada", "tags": ["a", "b"] }

Output

export interface Root {
  id: number;
  name: string;
  tags: string[];
}

Ek flat JSON object ek single typed interface ban jaata hai.

Common errors aur troubleshooting

  • Output line aur column ke saath Invalid error dikhata hai. — JSON mein syntax issue hai jaise trailing comma, single quotes ya unquoted key. Reported line aur column par theek karein, phir interfaces dobara generate ho jaayenge.
  • Aapke expected field ko question mark ke saath optional mark kiya gaya hai. — Woh key aapke array sample ke kam se kam ek element mein absent hai. Agar woh hamesha required honi chahiye to use har element mein shaamil karein.
  • Ek property unknown type ke roop mein aati hai. — Us key ki har sample value null ya undefined thi, isliye koi concrete type infer nahi ho saka. Us field ke liye real value wala sample dein.
  • Number ya string jaisi bare value paste karne par sirf ek type alias milta hai. — Yeh expected hai. Agar single export type alias ki jagah named interface chahiye to value ko object ya array mein wrap karein.

Aksar pooche jaane wale sawaal

JSON to TypeScript converter kya hai?
Yeh ek tool hai jo ek sample JSON object ya array padhta hai aur matching TypeScript interfaces generate karta hai, har field ka type infer karta hai taaki aap result ko seedha apne codebase mein drop kar sakein.
JSON ko TypeScript interfaces mein kaise convert karein?
Apna JSON input box mein paste karein, optionally Root interface name set karein, phir output panel se generate hue interfaces copy ya download karein.
JSON to TypeScript objects ke arrays ko kaise handle karta hai?
Yeh har element ki keys ko ek interface mein merge karta hai. Kuch elements mein missing koi bhi key question mark ke saath optional mark hoti hai taaki type poore array ko cover kare.
Nested objects TypeScript mein kaise convert hote hain?
Har nested object PascalCase name ke saath apna exported interface ban jaata hai, aur parent shape ko inline karne ki jagah use type se reference karta hai.
Null ya mixed-type values ke saath kya hota hai?
Null values null ke saath ek union banati hain, aur ek se zyada primitive type wale fields ek union ban jaate hain jaise string | number.
JSON ko TypeScript mein convert karte waqt mera JSON kahin bheja jaata hai kya?
Nahi. JSON to TypeScript conversion poori tarah aapke browser mein chalta hai, isliye aap jo data paste karte hain woh locally process hota hai aur device se bahar nahi jaata.
