Just read both of them and then write the values to the same file you want.

If those are *.XLSX files, you can use , you can use Open XML SDK:
http://www.microsoft.com/en-us/download/details.aspx?id=30425[^].

This way, you can support new XML-based Office formats (such as .DOCX, .XLSX), ECMA-376 standard:
http://en.wikipedia.org/wiki/Microsoft_Office_XML_formats[^],
http://en.wikipedia.org/wiki/Office_Open_XML[^].

This way, you can work without Office installed. Also, the documents are supported by 3rd-party software. Please see my past answers:
Convert Office-Documents to PDF without interop[^],
Need a rather unique WPF text editor control[^],
Hi how can i display word file in windows application using c#.net[^],
Read a word file without using Interop.word dll...Do not want to install word in IIS..[^].
