Answer 1

I am not sure the "Convert" is efficient. Is there anyway I could do this faster?

What makes you believe this? I promise you that Convert.ToString() is the most effective method in the code you posted. Your problem is that your looping through 180,000 records in an excel document...

You could split the work up since you know the number of row this is trival to do.

Why are you coverting Value2 to a string exactly?
