Let’s have a look at the steps required to create a VBA macro in a Word document.

  • First, load the Word document or create a new one using the Document class.
  • Then, create an object of VbaProject class, set its name, and assign it to the document using setVbaProject() method.
  • Create an object of the VbaModule class, and set its name, type, and source code.
  • Add module to the project using Document.getVbaProject().getModules().add(VbaModule) method.
  • Finally, save the Word document using Document.save() method.

The following code snippet shows how to create a VBA module in a Word document in Java.

Read a VBA Macro from a Word Document

You can access and read existing VBA macros from a Word document. For this, you need to load the document and access the modules’ collection in the VBA project. Below are the steps to read all VBA macros in a Word document.

  • Load Word document using Document class.
  • Access the collection of VBA modules using Document.getVbaProject().getModules() method.
  • Use VbaModule class to read each VBA module in the project.

Update a VBA Macro in a Word Document

In case you need to update the source code or any other information of a VBA module, you can do it effortlessly. Just access the desired VBA module from the collection and modify it as needed. The following are the steps to update a VBA macro in a Word document.

  • First, load Word document using Document class.
  • Access the collection of VBA modules using Document.getVbaProject().getModules() method.
  • Get the reference of the desired VBA macro in a VbaModule object.
  • Update the VBA module using VbaModule object.

The following code sample shows how to update a VBA macro in a Word document using Java.

Clone VBA Code from a Word Document

Aspose.Words for Java also lets you clone VBA macros from one Word document to another. You can clone either a complete VBA project or a specific VBA module. Let’s have a look at how to copy VBA in both cases.

Clone VBA Project from a Word Document

Here are the steps to clone a complete VBA project in a Word document.

  • Load source and target Word documents using Document class.
  • Call target.setVbaProject(source.getVbaProject().deepClone()) method to clone VBA project from source to target document.
  • Save the target document using Document.save() method.

The following code snippet clones the VBA project from one Word document to another.

Clone VBA Module from a Word Document

The following are the steps to a clone VBA module from one Word document to another in Java.

  • Load source and target Word documents using Document class.
  • Get clone of the desired VBA module in a VbaModule object using Document.getVbaProject().getModules().get(string Name).deepClone() method.
  • Add cloned VBA module into the target document using target.getVbaProject().getModules().add(VbaModule) method.
  • Save the target document using Document.save() method.
