When I set format of a cell as %, and Export it automatically multiply the value with 100 & show the value. So 1.9 becomes 190%, I have use this code to add Symbol of %.
worksheet.Cell(2, 2).Style.NumberFormat.SetFormat("0.00%");
Can anybody help me to solve this?
Finally Got a solution by Own. You can do it in a simple way. If you want to apply it on single cell then do this,
worksheet.Cell(9, 10).Style.NumberFormat.Format = "#,##0.00\\%";
And If you want to apply it on a Range of Cells then do this,
worksheet.Range(9, 10, 15, 10).Style.NumberFormat.Format = "#,##0.00\\%";
you can also find more formats Here, and also you can find the same from Excel as well.
