I have followed the code from How to automatically import data from uploaded CSV or XLS file into Google Sheets, but it does not explain how to find the folder ID that the file has been uploaded to.
I need to provide a spreadsheet template for multiple users that will facilitate the identification of the folder, since I have no way of knowing for sure where each user will save the csv file. I wish to avoid mistakes identifying the destination folder.
How can I obtain the ID of the folder where the user is importing their data?
