Steps to convert word document to PDF in AWS Elastic Beanstalk

Step 1: Create a new ASP.NET Core Web application (Model-View-Controller) project.

Step 2: Install the following Nuget packages in your application from Nuget.org.

• Syncfusion.DocIORenderer.Net.Core

Step 4: A default action method named Index will be present in HomeController.cs. Right click on Index method and select Go To View where you will be directed to its associated view page Index.cshtml.

Step 5: Add a new button in the Index.cshtml as shown below.

C#

@{
    Html.BeginForm("ConvertWordtoPDF", "Home", FormMethod.Get);
    {
        <div>
            <input type="submit" value="Convert WordtoPDF" style="width:150px;height:27px" />
        </div>
    }
    Html.EndForm();
}

C#

public IActionResult ConvertWordtoPDF()
{
    try
    {
        using (FileStream fileStreamPath = new FileStream(Path.GetFullPath("wwwroot/Data/Input.docx"), FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
        {
            //Loads the template document.
            using (WordDocument document = new WordDocument(fileStreamPath, FormatType.Docx))
            {
                //Hooks the font substitution event.
                document.FontSettings.SubstituteFont += FontSettings_SubstituteFont;
                using (DocIORenderer render = new DocIORenderer())
                {
                    // Converts Word document into PDF document. 
                    using (PdfDocument pdf = render.ConvertToPDF(document))
                    {
                        MemoryStream memoryStream = new MemoryStream();
                        //Saves the PDF file.
                        pdf.Save(memoryStream);
                        //Unhooks the font substitution event after converting to PDF.
                        document.FontSettings.SubstituteFont -= FontSettings_SubstituteFont;
                        memoryStream.Position = 0;
                        //Download PDF document in the browser
                        return File(memoryStream, "application/pdf", "Sample.pdf");
                    }                               
                }                           
            }                      
        }                 
    }
    catch (Exception ex)
    {
        ViewBag.Message = ex.ToString();
    }
    return View("Index");
