To format JSON, paste it and select Format. Valid JSON is pretty-printed with your chosen indentation; invalid JSON shows exactly where the problem is — for example “line 3, column 12: unexpected }” — with hints for common mistakes like trailing commas or single quotes.

गोपनीयता और फ़ाइल प्रबंधन
- यह कहाँ चलता है
- आपके ब्राउज़र में चलता है
पूरी तरह आपके ब्राउज़र में चलता है। आपकी फ़ाइलें और टेक्स्ट हमारे सर्वर पर अपलोड नहीं होते।

- Numbers beyond JavaScript’s safe integer range may lose precision when formatted.
अक्सर पूछे जाने वाले प्रश्न
What are the most common JSON errors?
Trailing commas, single quotes instead of double quotes, missing quotes around keys, and comments. The error message points to the exact position.
Is it safe to paste API keys or tokens?
Everything runs in your browser and nothing is sent anywhere. Still, avoid pasting secrets on shared computers.
