Managing inventory data in Excel often becomes difficult when daily usage and receipt records accumulate over time.
In this example, Power Query automatically creates a monthly inventory summary report.
The process includes:
- Replacing null values with zero
- Extracting month numbers from dates
- Grouping data by month and year
- Calculating total receipts
- Summing product usage
- Retrieving the latest stock value
- Creating a total usage column
The final result provides a clean monthly inventory report that updates automatically with Refresh.
This method is useful for warehouse management, stock analysis, production tracking, and Excel reporting automation.
