Answer 1

What you are doing should work if you wrote the output to a text file. Using CSV ( wikipedia ) you can easily export your data to Excel. See this link , due to the lack of standard, using tabs like you do should work.

You simply need to output the data row by row, using a separator (usually , , ; or tab ) and use a new line to define a new row.

Excel supports CSV files as Text Files . I don't have Excel on this PC, but usually there's an import wizard to help you with the creation of columns.

Answer 2

I would recommend looking at EPPlus

We've used this library extensively for generating complex Excel workbooks including pivot tables. Usage is very straightforward with plenty of examples and help on codeplex site.

I hope this helps!
