How to export a word document in asp.net using C#

If you do not have MS Office on server, where your ASP.NET application is hosted, you will not be able to use Word Interop in .NET.

In that case there are few options you can try, for example you can use this .NET component for word files together with a template file.

That would be one of the simplest ways and additionally you could import that admins data via mail merge process in C#, something like this:

DocumentModel doc = DocumentModel.Load(Server.MapPath("~/Template.docx"));
 
doc.MailMerge.Execute(
    new
    {
        empid = 14,
        sysno = 7,
        task = "design"
    });

And last you can simply export your DOCX file in ASP.NET to the employee like the following:

doc.Save(this.Response, "Employee Report.docx");

Application WordApp = new Application();
Document document = WordApp.Documents.Add(ref missing, ref missing, ref missing, ref missing);
Range rng = document.Range(ref start1, ref missing);

rng.Font.Name = "Arial";
rng.InsertAfter("Hi, this is Jignesh Trivedi.");
object filename = @"D:\MyTestDoc.doc";
document.SaveAs(ref filename, ref missing, ref missing, ref missing, ref missing, ref missing,
ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing);
WordApp.Visible = true;
