Export variable from ene module to google spreadsheet, and importing it in another module

Hi all

I am working on a project, which consist of a number of small e-learning modules. I have implemented a notepad. I would like for the content of the note pad to follow the  learner from one module to the next. 

I already have a functionality for exporting variables from the module to google sheets, but I lack a function to import the correct cell in the sheet to another module.

Does anyone have an idea as to how to do that?

Thanks in advance!
