Docx insert at merge field

Is there a way to insert a docx string into an existing document at a specific merge field. I have used DocumentBuilder.InsertHtml in IFieldMergingCallback.FieldMerging for html, however I need the same functionality only inserting docx. Is this possible?

Thanks

Hello

Thanks for your request. Yes of course you can insert any Document at a merge field using Aspose.Words and a little code. I think information provided in this thread will be useful for you:
