• Create an object of VbaProject class.
• Set name of the project using VbaProject.name property.
• Assign project to Document.vba_project property.
• Create an object of VbaModule class.
• Set name and type of module using VbaModule.name and VbaModule.type properties, respectively.
• Set source code using VbaModule.source_code property.
• Add module to the VBA project of the document using Document.vba_project.modules.add(VbaModule) method.
• Save the document using Document.save() method.
