Hi,
Hi Gary,
You cannot use MS Word to open Excel or PowerPoint documents. Same is the case with Aspose. You need Aspose.Words to convert Word documents to PDF, Aspose.Cells to convert Excel documents to PDF and Aspose.Slides to convert PowerPoint documents to PDF. Only Aspose.Words will not be enough to convert all documents.
Regarding PDF/A conversion, the Save methods exposed by Aspose.Words, Aspose.Cells and Aspose.Slides allow you to specify save options. You can use PdfSaveOptions exposed by Aspose.Words and Aspose.Cells, and PdfOptions exposed by Aspose.Slides to set Compliance to PDF/A. Aspose.Pdf is not required in this case to convert to PDF/A.
When three or more Aspose APIs are required in your applications, it is recommended to go for Aspose.Total in such cases because there is not much difference in price if you go for Aspose.Total or three individual APIs. Once you have Aspose.Total, you can also use Aspose.Pdf to convert PDF to PDF/A as it supports more options while converting PDF to PDF/A.
Best Regards,
Great! Very clear explanation. Thank you very much.
