Answer 2

Alternatively you can look at using OleDB to do this

Reading and Writing Excel Spreadsheets Using ADO.NET

I've used this method a number of times and found it to be quick and effective.

3rd Alternative, if it doesn't have to be a true xls/xlsx file and you want lots of control over what the final output looks like, try Microsoft's Spreadsheet XML.

XML Spreadsheet Reference

Again, I've used this method to great effect

Answer 3

You can read from one source and update to another using DataSet, with 2 distinct tOleDb connections.

Here's some code that does that.
