Answer 1

I would recommend using the following technique:

1. http://kbcsv.codeplex.com/ this reads CSV files in very easily and is very robust.
2. Create a datatable from the csv via the kbcsv extensions.
3. Use the eppplus library and its LoadFromDataTable to create a valid xlsx file (https://github.com/JanKallman/EPPlus)
4. done!

Advantages:

• It is faster than excel interop
• KBCSV is more robust than excels csv reading methods.
• It is availabe in environments witohout office.
