Method 1: Using Formulas to Group Data by Week

One way to group data by week is by using formulas, specifically the WEEKNUM function. This function returns the week number of a given date, which can be used to group data.

Here's an example formula:

Select the data range, including the date column.
Go to the "Data" tab and click on "Group."
Select "Date" as the grouping option.
Choose "Week" as the grouping interval.

Tips and Variations

To group data by week with multiple criteria, use pivot tables with multiple fields in the "Row Labels" area.
