Convert DOCM to DOCX

On this page we will look at how to convert a document that contains VBA code and has a .docm extension to a .docx document. With this conversion, macros and vbaProject parts stored in a document in DOCM format will not be written to the DOCX.

Aspose.Words

In Aspose.Words, we normally use the Document constructor of Aspose.Words API to load a document in DOCM format and the Document.Save method to save the document to DOCX.

The following code example shows how to convert DOCM to DOCX:

// For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-.NET.git.
Document doc = new Document(MyDir + "Docm to Docx.docm");
doc.Save(ArtifactsDir + "Docm to Docx - Aspose.Words.docx");

Open XML SDK

You can also do the same using the Open XML SDK. At the same time, note that it looks somewhat more complicated and more cumbersome.

The following code example modifies the specified document by verifying that the document contains a vbaProject part and removing that part. After the code removes the part, it changes the document type internally and renames the document so that it uses .docx extension.

// For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-.NET.git.
string docmFilePath = MyDir + "Docm to Docx.docm";
string docxFilePath = ArtifactsDir + "Docm to Docx - OpenXML.docx";

using (WordprocessingDocument docm = WordprocessingDocument.Open(docmFilePath, false))
{
    // Create a copy of the .docm file as .docx.
    File.Copy(docmFilePath, docxFilePath, true);

    // Open the new .docx file and remove the macros.
    using (WordprocessingDocument docx = WordprocessingDocument.Open(docxFilePath, true))
    {
        // Remove the VBA project part (macros).
        VbaProjectPart vbaPart = docx.MainDocumentPart.VbaProjectPart;
        if (vbaPart != null)
            docx.MainDocumentPart.DeletePart(vbaPart);

        // Change the document type to .docx (no macros).
        docx.ChangeDocumentType(WordprocessingDocumentType.Document);
    }
}

You can download the sample file of this example from Aspose.Words GitHub.
