  • 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.

The following code sample shows how to create a VBA macro in a DOCM document using Python.

Modify VBA Macro in a Word Document in Python

You can also access and modify the existing VBA macros in Word documents seamlessly. The following steps demonstrate how to achieve this using Aspose.Words for Python.

  • Load the Word document using Document class.
  • Get reference of the VbaProject into an object using Document.vba_project property.
  • Access the desired VBA module using index and update its source code using VbaProject.modules[int].source_code property.

  • Load the destination Word document using Document class.
  • Create a VbaProject for destination Word document.
  • Get clone of VBA module from source Word document into an object using Document.vba_project.modules.get_by_name(string).clone() method.
  • Add the cloned module into destination document using Document.vba_project.modules.add(VbaModule) method.
  • Save the destination document using Document.save() method.

The following code sample shows how to clone an MS Word VBA module in Python.

Clone a VBA Project

The following are the steps to clone an MS Word VBA project in Python.

  • Load the source Word document using Document class.
  • Load the destination Word document using Document class.
  • Get clone of VBA project from source document using Document.vba_project.clone() method and add it to destination document using Document.vba_project property.
