Syncfusion^® XlsIO is a .NET Core Excel library can be used to create, read, edit Excel files. This library supports manipulating Excel documents in AWS Elastic Beanstalk.

Steps to create an Excel document in AWS Elastic Beanstalk

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

Step 2: Install the Syncfusion.XlsIO.Net.Core NuGet package as a reference to your project from NuGet.org.

NOTE

Starting with v16.2.0.x, if you reference Syncfusion^® assemblies from trial setup or from the NuGet feed, you also have to add “Syncfusion.Licensing” assembly reference and include a license key in your projects. Please refer to this link to know about registering Syncfusion^® license key in your application to use our components.

Step 3: Include the following namespaces in the HomeController.cs file.

C#

using Syncfusion.XlsIO;

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("CreatExcelDocument", "Home", FormMethod.Get);
    {
        <div>
           <input type="submit" value="Create Excel document" style="width:200px;height:27px" />
        </div>
    }
    Html.EndForm();
}

Step 6: Add a new action method CreateExcelDocument in HomeController.cs and include the below code snippet to create an Excel document and download it.

C#

//Create an instance of ExcelEngine
using (ExcelEngine excelEngine = new ExcelEngine())
{
    IApplication application = excelEngine.Excel;  
    application.DefaultVersion = ExcelVersion.Xlsx;

Read and Edit Excel file

The below code snippet illustrates how to read and edit an Excel file in AWS Elastic Beanstalk.

C#

using (ExcelEngine excelEngine = new ExcelEngine())
{
    //Instantiate the Excel application object
    IApplication application = excelEngine.Excel;

    //Assigns default application version
    application.DefaultVersion = ExcelVersion.Xlsx;

    //A existing workbook is opened.             
    IWorkbook workbook = application.Workbooks.Open("Data/InputTemplate.xlsx");

    //Access first worksheet from the workbook.
    IWorksheet worksheet = workbook.Worksheets[0];

    //Set Text in cell A3.
    worksheet.Range["A3"].Text = "Hello World";
    //Saving the Excel to the MemoryStream 
    MemoryStream stream = new MemoryStream();
    workbook.SaveAs(stream);

    //Set the position as '0'.
    stream.Position = 0;

    //Download Excel document in the browser.
