I try to pull out data using Excel which contains ISO code. I attach Excel file and data. Need to pull out particular countries like UK and Sweden:
1. grouping your numbers to decrease the row size (country based according to ISO).
2. calculate a weekly average instead of displaying daily cases.

Source dataset:

Need help how to do it.
