Excel 12.0 Object Library speed

I'm writing a C# program that outputs thousands of lines into an excel spreadsheet using the Excel 12.0 Object Library. I noticed that it was generally pretty slow, so I timed it with the Stopwatch class and found out each write to a ce开发者_如何学Pythonll was taking around 4 million ticks.

1. Is this speed normal?
2. Is there a faster alternative?

Edit: 4 not 100 million

Yes, this speed is normal - it is painfully slow.

There are faster alternatives available. I have used SpreadsheetGear, which I found easy to use and much faster.

Maybe look at the question. Create excel xls and xlsx a lot of people liked the Epplus library. I just started with it and it seems good.
