Introduction

Here you can simply export a excel using excel template like html template. You will never need to set cell styles in your code. Instead, all the cell styles and expressions can be set in the excel visibly. You will only need to code like this:

var tpl = new ExcelTemplate("tpl.xls");
tpl.Values.Add("order", order);
tpl.SaveAs("newfile.xls");
