Question

I am Export a data to Excel Sheet in C#.Net. There i am having column which has the data like “00123450098”. The data is exported without the first zero’s. I want to show the data as it is.

Here is my export excel code.

 string style = @"<style> .text { mso-number-format:\@; } </style> ";
    HttpContext.Current.Response.Clear();
    HttpContext.Current.Response.AddHeader(
        "content-disposition", string.Format("attachment; filename={0}", fileName));
    HttpContext.Current.Response.ContentType = "application/ms-excel";
    HtmlForm frm = new HtmlForm();
    ...................
    ...................
     table.RenderControl(htw);
            HttpContext.Current.Response.Write(style);
            //render the htmlwriter into the response
            HttpContext.Current.Response.Write(sw.ToString());
            HttpContext.Current.Response.End();

Answer 1

In Excel file, Numbers cell always strips the leading zeros, you can set numbers with leading zeros by following a single quote. i.e.

00123450098 to ‘00123450098

but then, the format for that cell will changes to text.
If your generated excel file, have any formula, which is include that cell reference as number then it will not work as expected.
