How to keep some data in the workspace when clear all?

I have a huge data which takes time to load, therefore, I do not want to remove it from the workspace everytime I run the code but I want to clear the workspace from the data produced by the code itself.

You can delete specific variables using clearvars. You have many other options along with that. Read it here.
