Convert docx to xlsx

Question

Hello,

I am writting .NET application that generates reports in docx. One of the last requirements I've got was - generate also these reports in xlsx format. So, is there any simple way to convert docx to xlsx format? I haven't found any solution or utility/library. One of the ideas was to use Microsoft.Office.Interop Copy/Paste methods, but I don't know if it helps :)

We have used a MS tool that allows you to work with Office documents as if they were xml:

Open XML SDK 2.0 for Microsoft Office

This had the following benefits compared with interop:

• No need in install office
• No problems with memory due to Excel not closing
• Better performance, in our case it went from 40 seconds to 2 (two)
