Group A
Pivot Table in Excel
When analyzing data in Excel, it is often useful to group a pivot table.
For
example, instead of displaying total sales values for individual days, you
might prefer to group the days and display the total sales values by month.
Excel can
automatically group numeric values (including dates & times) in pivot
tables. This is shown in the following examples.
Example 1: Group a Pivot Table by Date
Imagine
you have created the pivot table on the left, which shows sales figures for each date
of the first quarter of 2016.
If you
want to group the sales figures by month, you can do this as follows:
Right
click on left column of the pivot table (containing the dates) and select the
option Group...;
You will
be presented with the 'Grouping' dialog box for dates;
Select
the value Months and click OK.
|
This will
group the figures by month, as shown in the pivot table below.
Example 2: Group a Pivot Table by Range
Imagine
you have created the pivot table on the left, which groups 150 children according to
age. The ages range from 5 to 16 years.
If you
want to group the ages into the age ranges 5-8 years, 9-12 years and 13-16
years, you can this as follows:
Right
click on left column of the pivot table (containing the ages) and select the
option Group...;
You will
be presented with the 'Grouping' dialog box for numbers;
Excel
will automatically enter the minimum and maximum values from the data, (which
in this case are of 5 and 16);
We want
to group the ages into 4-year periods, so we change the value in the lower
box (labelled By:)
to a 4;
Click OK.
|
This will
group the ages into categories, beginning with age 5-8 and increasing by 4
years each time. The resulting pivot table is shown below:
Ungrouping a Pivot Table
To ungroup
the values in a pivot table, simply:
Right
click on left column of the pivot table (containing the grouped values);
Select the
option Ungroup...
Common Pivot Table Grouping Error
Pivot Table Grouping Error: Cannot Group That
Selection
If you
attempt to group a pivot table, but find that the Group...option is greyed
out, or that a message box pops up, saying "Cannot Group That
Selection", this is usually because the data column in the original data
sheet contains one or more non-numeric values (or non-date values), or errors.
In order
to fix this, you will need to return to your original data sheet and amend the
non-numeric or non-date values.
Once you
have done this, right click on the pivot table and select Refresh. This will
update the values in the pivot table, and you should now be able to group the
selected row or column values.
