Hi,

you can export to Word in ASP.NET or Windows application with this C# / VB.NET Word library.

Here is a sample C# code how to export DataGridView to Word file with .NET mail merge functionality:

// Use the component in free mode.
ComponentInfo.SetLicense("FREE-LIMITED-KEY");

// Create and save a template document. 
// You don't have to do this if you already have a template document.
// This code is only provided as a reference how template document should look like.
var document = new DocumentModel();
document.Sections.Add(
  new Section(document,
    new Table(document,
      new TableRow(document,
        new TableCell(document,
          new Paragraph(document, "Name")),
        new TableCell(document,
          new Paragraph(document, "Surname"))),
      new TableRow(document,
        new TableCell(document,
          new Paragraph(document,
            new Field(document, FieldType.MergeField, "RangeStart:People"),
            new Field(document, FieldType.MergeField, "Name"))),
        new TableCell(document,
          new Paragraph(document,
            new Field(document, FieldType.MergeField, "Surname"),
            new Field(document, FieldType.MergeField, "RangeEnd:People")))))));
document.Save("TemplateDocument.docx", SaveOptions.DocxDefault);

// Load a template document.
document = DocumentModel.Load("TemplateDocument.docx", LoadOptions.DocxDefault);

// Mail merge template document with DataGridView.DataSource.
// DataGridView.DataSource is a DataTable with two columns: 'Name' and 'Surname'.
// Important: rangeName parameter and RangeStart/RangeEnd merge field names must match.
document.MailMerge.ExecuteRange("People", dataGridView.DataSource);

// Save the mail merged document.
document.Save("Document.docx", SaveOptions.DocxDefault);
