How to paste into finished Excel from Codeigniter?

Question

CodeIgniter

Hello, I have a ready-made excel in which I need to fill in some cells. I found how to attach Phpexcel to the ignorer, but how to fill in the cells already in the finished file (you can say, as it were, in a template) is not clear.

A moment of poetry. I read questions like this and I'm blown away. How did people get to Codeigniter with questions like this?
On this topic. Author, your question is similar to the question "How do I program in php?". What does codeigniter have to do with it? In the Phpexecl documentation, everything is clearly described how to fill in the cells in the finished file. What is the problem?
