FAQ

JSON invalid kyun bata raha hai?

Common galtiyan: keys double quotes me nahi hain, aakhri item ke baad extra comma (trailing comma), single quotes ka use, ya comments — JSON me ye sab allowed nahi hai. Error message me exact position dikhta hai.

Kya mera JSON data kahin upload hota hai?

Nahi — parsing aur formatting browser me JSON.parse/JSON.stringify se hoti hai. API keys ya sensitive data wala JSON bhi safe hai.

Kitna bada JSON handle ho sakta hai?

Kai MB tak aaram se — browser me hi process hota hai. Bahut bade files (50MB+) pe tab slow ho sakta hai.

JSON5 ya JSONC (comments wala) support hai?

Nahi — ye strict JSON validator hai (RFC 8259). Comments aur trailing commas standard JSON me invalid hain, isliye error milega.
