Grouping by month in Excel Pivot Table requires you to make sure that the date is formatted correctly, then insert the Pivot Table and add the date field, and finally right-click the group to select "Month" aggregation. If you encounter problems, check whether it is a standard date format and the data range are reasonable, and adjust the number format to correctly display the month.
Grouping by month in Excel's pivot table is actually a very common requirement, such as if you want to count monthly sales, order volume, etc. The operation is not difficult, but if you are not familiar with it, it may get stuck, especially when there is a problem with the data format or time dimension.

Make sure the date format is correct
This is the most critical step. To be able to group by month, your date column must be in the "standard date format" recognized by Excel. If your data looks like dates, but Excel doesn't let you group by month, it's likely to be a "text-type date".

How to check?
Select a date cell and see if it is displayed in the formula bar in a format similar to "2024/1/1" or "2024-01-01". If not, it could be text.
How to convert?
You can use the VALUE()
or DATEVALUE()
function to convert, or use the "Class" function in the "Data" menu to select the "Date" format step by step.

Insert the pivot table and add the date field
This step is more routine:
- Select your data area (it is recommended to use table format, i.e. Ctrl T)
- Insert > Pivot Table
- Drag into your date field in the Row area
At this time, what you see may be a bunch of specific dates, rather than the results summarized by month.
Right-click to group and select "Moon" to aggregate
Next is the key operation:
- Right-click any date in the pivot table (such as a certain day)
- Select Group
- Check "Month" in the pop-up window (you can also select year, quarter, etc. at the same time)
- Click OK and you will find that the date has become a monthly display
Note: If you can't see the "Group" option, it's most likely that it's because the date format is wrong. Go back and check the first step.
What to do if you encounter problems?
Sometimes I encounter some small pitfalls:
- Date fields cannot be grouped : Go back to the first step and confirm whether they are in the true date format.
- There is no option for "month" after grouping : it is possible that your data only contains the same month, or the span is too short, so you can try to expand the scope of the data.
- The number is displayed instead of the month name : right-click the date line, select "Field Settings", and change it to your favorite date format in "Number Format", such as "yyyy-mm" or "mmm-yyyy".
Basically these steps. The operation itself is not complicated, but the date format requirements are quite strict. Just make sure that the dates in the original data are in standard format, and the rest is something you can do with just a few clicks of the mouse.
