Pivot table group by day of week
To group a pivot table by day of week (e.g. Mon, Tue, Wed, etc.) you can add a helper column to the source data with a formula to extract the weekday name, then use the helper to group data in the pivot table. In the example shown, the pivot table is configured to display sales by weekday. Note that Excel automatically sorts standard weekday names in a natural order, instead of alphabetically.
Pivot Table Fields
In the pivot table shown, there are four fields in use: Date, Area, Sales, and Day. Three of these fields are used to create the pivot table shown: Area is a Row field, Day is a Column field, and Sales is a Value field, as seen below.
When the Sales field is first added as a Value field, it is automatically named "Sum of Sales". In the example, it has been renamed "Sales ", with a trailing space to prevent Excel from complaining that the name is already in use.
The formula used in E5, copied down, is:
