- Excel
- Device & OS
- not provided
- Scenario
- Processing employee attendance and payroll records to break down daily hours.
- Observed behavior
- The data needs to be reshaped to show specific breakdown rows, and any missing dates must be populated and filled with zero hours.
Ensure your source data is formatted as an Excel Table (Ctrl+T) before importing it into Power Query. This ensures that any new attendance records added later will automatically flow into your reshaped output.
Use Power Query to Unpivot and Group Data
Power Query is the most reliable method to reshape data, handle missing dates, and generate automatic summary rows.
By utilizing Power Query's unpivot and grouping features, you can dynamically transform wide columns into neat rows without writing complex formulas. This approach also allows you to merge a calendar table so missing dates reflect zero hours.
Select your source table, navigate to the Data tab, and click 'From Table/Range' to open the Power Query Editor.
Select the OT and Normal hours columns, right-click the headers, and choose 'Unpivot Columns'. Rename the newly created columns to 'Hour Type' and 'Hours'.
Create a separate query containing a complete list of dates and merge it with your employee list. Merge this combined list with your unpivoted source data to ensure all dates are covered.
Select the 'Hours' column, go to the Transform tab, click 'Replace Values', and replace 'null' with '0' to fill in the missing dates.
Create a reference of your current query, group the data by Employee ID and Date to calculate the Sum of Hours, and label this group 'Total'. Append this grouped query back to your main unpivoted query.
Go to the Home tab and click 'Close & Load' to output the reshaped three-row format back into an Excel worksheet.
Reshape Data Using Dynamic Array Formulas
If you prefer not to use Power Query, modern Excel versions support dynamic arrays to stack and calculate data directly on the sheet.

Frequently Asked Questions
Why are missing dates not showing up in my output?
To display missing dates, you need to create a complete calendar table and perform a Left Outer merge with your existing attendance data. After merging, you can replace any resulting null values with zeros.
Can I automate this process for future months?
Yes. By using Power Query, you set up the transformation steps once. When you paste new attendance data into your source table, simply click 'Refresh All' on the Data tab to instantly update the final output.
Is it possible to separate different types of overtime, like 1.5x and 2.0x?
Absolutely. In Power Query, simply include all your specific overtime columns when you select the columns to unpivot. The system will automatically create separate rows for each overtime category alongside the normal hours.
