Hi Great tutorial, however I do have a question regarding the VS Code. My VS code can't autofill like yours can, how do you achieve the autofill? Thank you.

Hi, thank you. This tutorial is amazing.
but instead of creating a new excel file, is there anyway to modify a specific cell in a existing Excel file?
