Sé mostrar mi Parse Json en la celda Excel cuando el Json es "simple" (cuando es solo una cadena dentro) pero ahora tengo String, object y array y estoy un poco perdido ... mi json está siguiendo:

Me gustaría acceder a lo que quiero y mostrarlo en la celda, pero no sé el acceso en la matriz y el objeto.

¡Gracias a todos
