Hello,
I have a sheet with around 3000 rows all of which have a date received and I am trying to count how many were received per week.
Currently I have a helper column which has the week number (1-52) and have =COUNTIF([Week number]@Row, =1) which works but I am wondering how to then extend the formula to automatically change the week number so the next row would be =COUNTIF([Week number]@Row, =2) and so on as I do not fancy manually changing the number 52 times.
Is there any way to automate this?
Cheers,
