However, Aspose.Cells APIs cannot directly convert Excel spreadsheets to Word documents. Just so you know, the spreadsheet management library Aspose.Cells exclusively handles MS Excel file formats. Another part of our system, called Aspose.Words, handles or merges MS Word documents. However, I believe that in order to meet your specific needs, you must utilize two Aspose APIs in two steps, namely Aspose.Cells & Aspose.Pdf. To convert spreadsheet formats (XLS/XLSX, etc.) to PDF format, you will use Aspose.Cells APIs. When you need to convert a PDF to a Word document, you can do so by using the Aspose.Pdf APIs.
