Hi Ajay, Use DocumentFormat.OpenXml To edit word document using (WordprocessingDocument doc = WordprocessingDocument.Create ("C:\Users\Administrator\Desktop\Test\WordTest.docx", DocumentFormat.OpenXml.WordprocessingDocumentType.Document)) { // Add a main document part. MainDocumentPart mainPart = doc.AddMainDocumentPart(); // Create the document structure and add some text. mainPart.Document = new Document(); Body body = mainPart.Document.AppendChild(new Body()); Paragraph para = body.AppendChild(new Paragraph()); Run run = para.AppendChild(new Run()); // String msg contains the text, "Hello, Word!" run.AppendChild(new Text("New text in document")); } To Save word file to pdf use Microsoft.Office.Interop.Word protected void SaveAsPDF_Click(object sender, EventArgs e) { Microsoft.Office.Interop.Word.Application application = new Microsoft.Office.Interop.Word.Application(); Document document = null; application.Visible = false; // open docx file document = application.Documents.Open("C:\Users\Administrator\Desktop\Test\WordTest.docx"); // convert to pdf file document.ExportAsFixedFormat("C:\Users\Administrator\Desktop\Test\WordTest.pdf", WdExportFormat.wdExportFormatPDF); document.Close(); }
