This brief tutorial directs to create pivot table in Python with the help of detailed steps providing information about the environment configuration and Python program flow. While using Python Excel pivot table will be created using a runnable sample code after loading the source workbook containing the input data for the pivot table. In the end, the resultant workbook will be saved in any of the desired formats like XLSX, XLS, etc.
Steps to Create Pivot Table in Python
- Establish the environment to install Aspose.Cells for Python via Java into the project
- Load or create a Workbook class object containing input data for the pivot table
- Get the reference to the pivot tables collection in the target worksheet
- Add a pivot table in the collection
- Configure the newly added pivot table
- Add the desired fields into respective areas in the pivot table
- Save the output workbook with the pivot table in it
These steps provide instructions for Python code to create pivot table in Excel by sharing a link to the environment configuration resource and to a sequence of tasks to be performed in Python to achieve the functionality. It guides to add fields to different areas in the pivot table as per the requirement. Once the pivot table is prepared, it is saved in the Excel file in the desired format.

| csvWorkbook.save("NewPivotTable.xlsx") | |
