How to pick a file from the path given in excel?

I am using robot framework, python3.
I am trying to do data driven automation script.
I stuck where I want to read the one cell of excel where the path of one text document has been mentioned. I want to upload that text document in my application.

I tried to use excel library but it is not allowing to do that.
I am using pycharm.
It is not showing library availability though I have installed library robot framework excel and other excel libraries.

How to meet this?
