Question 1

Is my JSON sent anywhere?

Accepted Answer

Never. Formatting uses your browser's built-in JSON engine, which matters when the data contains keys or customer details.

Question 2

Why does it say unexpected token?

Accepted Answer

Usually a trailing comma, a single quote instead of a double quote, or an unquoted key. The message points at the position that broke.

Question 3

Is it really free, and do I need an account?

Accepted Answer

Yes, it is completely free and there is no sign-up, watermark, email wall or daily limit.
