الأسئلة الشائعة

How does the validator pinpoint the exact line of syntax errors?

Built-in parser listeners catch syntax exceptions and calculate corresponding line and column numbers with descriptive diagnostics.

Is my sensitive JSON data sent to any remote server?

Never. Processing is 100% client-side in your browser and works completely offline without sending data over the network.
