how to read excel template from an excel file?

Question

I have an excel file with some template. I am given a requirement that the template can change.
So what I want to know is there any way I can read the template of that Excel file as it is and display that excel file excel sheet exactly to a GridView control in my webpage.
I want to read all the styles format basically. so that I can display it as it is in my GridView and ask my user to update in that gridview. So that later point I can save that GridView data in my database.
Thank you in advance.
