Although it may seems impossible, I installed Excel on a 2017 Nokia 3310. In this video I show how to do it, but in summary:
1. I downloaded the Excel .jar from "Phoneky"
2. I sent the file to the Nokia already equipped with a MicroSD via Bluetooth
3. I installed the .jar file that was just transferred
And there you go, now you have a Nokia 3310 with Excel
