title: convert special characters html to excel in vb.net
body: <p>I have a web page which I want to convert to excel. I have created an HTML file with a gridview and then convert it to excel. The problem is that in the excel file, some of the columns are shown in the general format and like this 6.5E15. However, they are credit card numbers and should not be shown this way. So the user has to change the cell format to number manually  to see the whole credit card number. What should I do to make this right in my code.</p>
