Questions

Is my JSON sent anywhere?

No. It is processed in this browser tab and is not uploaded or saved.

Can it fix broken JSON?

Yes. Use Try to repair: it lists each change it made, and you choose whether to use the repaired JSON.

What counts as a difference?

On the Compare tab, each added, removed or changed value is listed with its path. Key order is ignored, and you can ignore array order too.
