Slow LightSail instance when opening Excel

Hi, I don't know if you were able to finish your question here, but I would assume that you are running an Windows Lightsail instance that is too small for what you are trying to do. I would not go any lower than the $12/month version of Windows Lightsail, and would be more inclined to go even bigger. Excel likes RAM (memory), if it's taking a long time my guess is there is not enough memory and to try a bigger instance type.

Interesting. Have you looked at your task manager/process manager to see if something is consuming a lot of CPU? 16GB is plenty. If you click on your instance you can go to your monitoring metrics. Take a look through each of the different ones (CPU Utilization and others) feel free to screenshot and post here
