Convert docx to xlsx
I am writing a .NET application that generates reports in docx. One of the last requirements I got was to generate these reports in xlsx format. So, is there an easy 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 that helps :)

We used an MS tool that allows us to work with Office documents as if they were xml:
Open XML SDK 2.0 for Microsoft Office
This had the following advantages over interop:
- No need to set up an office.
- No memory issues due to closing Excel.
- The best performance, in our case it lasted from 40 seconds to 2 (two)
