| Column A | Column B |
| 14/4 | 1 |
| 15/4 | 100 |
| 16/4 | 70 |
| 17/4 | 80 |
What is the formula I could use to extract the data (column B) of previous weekday please? So if I open the file on monday (17 april), formula should return 1. If I open the file on tuesday (18 apr), formula should return 80.
Thanks in advance for your help.
