We need a C# program that would be able to convert excel files that are stored in a directory to CSV format.
1) 1) That program should be able to convert ANY file that is stored in a directory to CSV.
2) 2) The first line of the spreadsheet (A1, A2, A3, etc.) is where the field names are. Samples of the spreadsheets are attached.
3
3) The files can be either XLS or XLSX! (Very important)
4) ) The attached files will be used to test the program. Both in XLX and XLSX.
Constraints:
1) The program **CANNOT** depend on any Office component (because that server that will run this process **does not** have Office installed)
2) .NET Framework should be 3.51
