Use an Excel PivotTable to Group and Count Orders

Creating a PivotTable and grouping the dates by month is the most efficient way to track how often supply items are purchased over time.

PivotTables allow you to dynamically reorganize and summarize large datasets. By using the grouping feature on date fields, you can effortlessly consolidate daily transaction records into clean, monthly frequency reports.

Insert a PivotTable

Select your entire range of order data. Navigate to the 'Insert' tab on the ribbon and click 'PivotTable'. Choose to place the PivotTable on a New Worksheet and click 'OK'.

Add Fields to Rows

In the PivotTable Fields pane on the right side of the screen, drag your 'Product' (or item code) field into the 'Rows' area.

Group Dates by Month

Drag the 'Order Date' field into the 'Rows' area beneath the product. Right-click any date that appears in the PivotTable, select 'Group' from the context menu, select 'Months', and click 'OK'.

Move Months to Columns for Comparison

To view the data in a matrix format that compares ordering frequency side-by-side, drag the newly grouped 'Months' field from the 'Rows' area and drop it into the 'Columns' area.

Calculate the Order Frequency

Drag the 'Product' field (or a unique Order ID) into the 'Values' area. Ensure the calculation is set to 'Count of Product' so that Excel displays the number of times each item was ordered in each respective month.

Check Data Formatting: If the 'Group' option is grayed out when you right-click the date, it means Excel does not recognize one or more cells in your Date column as a valid date. Clear any text or empty cells in the original data source and refresh.

Frequently Asked Questions

Why can't I group dates by month in my PivotTable?

This typically occurs if your original date column contains blank cells, text values, or improperly formatted dates. Highlight your date column in the source data, apply a Short Date format, remove any text, and refresh the PivotTable.

How do I show products that weren't ordered in a specific month?

By default, PivotTables hide items with no data. To display them, right-click any product in your PivotTable, select 'Field Settings', navigate to the 'Layout & Print' tab, and check the box for 'Show items with no data'.

Can I calculate the total amount spent instead of the order frequency?

Yes. Instead of dropping the Product field into the Values area to get a 'Count', drag your 'Total Cost' or 'Price' column into the Values area. Ensure the summary function is set to 'Sum' to see the total expenditure per item by month.
