JSON Validator
Free JSON Validator: Check Syntax Errors & Debug Code Online
Kya aapne kabhi ghanto code likha, lekin run karne par "Syntax Error" aa gaya? JSON code ke sath kaam karte waqt ek chhota sa Comma (,) bhool jana ya Bracket } band na karna poore program ko crash kar sakta hai.
Insaan hone ke naate hazaron lines ke code mein us ek galti ko dhoondhna kisi 'bhuse ke dher mein sui dhoondhne' jaisa hai. InWebTools JSON Validator aapka smart debugger hai. Yeh aapke code ko scan karta hai aur aapko ungli rakh kar batata hai ki "Line 45 par galti hai, use theek karein."
🚫 JSON mein log aksar kya galtiyan karte hain?
JSON ke rules bahut sakht (strict) hote hain. Yeh Validator in common errors ko pakadta hai:
- Trailing Commas: List ke aakhri item ke baad comma lagana mana hai (e.g.,
{"id": 1,}galat hai). - Single Quotes: JSON mein Keys aur Values hamesha Double Quotes
" "mein honi chahiye. Single quotes' 'valid nahi hain. - Missing Brackets: Curly braces
{}ya Square brackets[]ka open hokar close na hona.
🚀 Validator ki zarurat kyu hai?
- API Testing: Postman ya Server par data bhejne se pehle check karein ki format sahi hai ya nahi.
- Configuration Files: Bahut saare softwares (jaise VS Code settings) JSON mein hote hain. Ek galti se software kaam karna band kar deta hai.
- Learning: Naye students ke liye yeh samajhne mein madad karta hai ki unka code kyu nahi chal raha.
🛠️ JSON Code ko Validate kaise karein?
- Code Paste Karein: Editor mein apna JSON data dalein.
- Validate Click Karein: Button dabayein.
- Result Dekhein:
- Agar sab sahi hai: "Valid JSON" ka message aayega.
- Agar galti hai: Error Message aayega jo batayega ki kis line number par kya miss hua hai.
Frequently Asked Questions (FAQs)
Q: JSON aur JavaScript Object mein kya farak hai?
A: JavaScript mein keys bina quotes ke ho sakti hain (e.g., {name: "John"}), lekin JSON mein keys ko quotes mein hona zaruri hai (e.g., {"name": "John"}). Hamara tool isi rule ko check karta hai.
Q: Kya yeh tool errors ko automatically fix karta hai?
A: Yeh ek Validator hai, "Auto-Fixer" nahi. Yeh aapko galti batata hai taaki aap seekh sakein aur use khud theek karein. Auto-fix kabhi-kabhi data corrupt kar sakta hai.
Q: "Unexpected token" error ka kya matlab hai?
A: Iska matlab hai ki code mein koi aisa symbol (character) hai jo wahan nahi hona chahiye tha. Aksar ye extra comma ya missing quote ki wajah se hota hai.

Enjoy the little things in life. For one day, you may look back and realize they were the big things. Many of life's failures are people who did not realize how close they were to success when they gave up.
