Is there a way for google appscript to access local files? If not, why isn't this possible?
My end goal is an app script that can:
1. Read a local excel file
2. Select certain cells from the excel file
3. Copy them into a google sheet.
The hardest part I'm struggling with is reading a local file. I do not want to have to upload every excel file because I download 10s of them a day.
