Questions

Is my data uploaded?

No. Formatting and validation run in your browser, and nothing leaves your device.

Why does my JSON fail to parse?

The usual causes are trailing commas, single quotes, unquoted keys and comments. Standard JSON allows none of them. The error message shows the line and column to fix.

Does sorting keys change my data?

Only the order of keys inside objects. Values and array order stay the same.
