Create Google Sheets Macro/Javascript

I need a script that will check a folder for the newest spreadsheet, take the data in the spreadsheet and import that data into a specific sheet. Basically, a file is being uploaded into my drive everyday and I need a spreadsheet to fill in a bunch of cells based on the data in the updated spreadsheet. I'm not sure if the spreadsheet should import that data or if i should adjust all of my functions to look at the data at the updated URL based on the newest file.
