Steps to download Excel document in Azure platform programmatically:
Prerequisites:
- Visual Studio 2017 with Azure development.
- An Azure subscription or a free account.
Step 1: Create a new ASP.NET Web application project and add code snippet to create Excel using XlsIO
Create a new ASP.NET web application
1. Install the Syncfusion.XlsIO.Base NuGet package as a reference to your .NET Framework applications from the NuGet.org.
Install NuGet package
2. Add a new Web Form in the ASP.NET project. Right-click on the project and select Add > New Item and add a Web Form from the list. Name it as MainPage.
3. Add a new button in the MainPage.aspx as shown below.
CSHTML
<html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> <asp:Button ID="Button1" runat="server" Text="Create Document" OnClick="OnButtonClicked" /> </div> </form> </body> </html>
4. Include the following namespace in your MainPage.aspx.cs file.
C#
using Syncfusion.XlsIO;
VB.NET
Imports Syncfusion.XlsIO
5. Include the below code snippet in the click event of the button in MainPage.aspx.cs, to create an Excel file and download it.
C#
// Create an instance of ExcelEngine
using (ExcelEngine excelEngine = new ExcelEngine())
{
// Set the default application version as Excel 2016
excelEngine.Excel.DefaultVersion = ExcelVersion.Excel2016;
// Create a workbook with a worksheet
IWorkbook workbook = excelEngine.Excel.Workbooks.Create(1);
// Access the first worksheet from the workbook instance
IWorksheet worksheet = workbook.Worksheets[0];
// Insert sample text into cell “A1”
worksheet.Range["A1"].Text = "Hello World";
// Save the workbook to disk in xlsx format
workbook.SaveAs("Output.xlsx", Response, ExcelDownloadType.Open, ExcelHttpContentType.Excel2016);
}
VB.NET
'Create an instance of ExcelEngine
Using excelEngine As ExcelEngine = New ExcelEngine
'Set the default application version as Excel 2016
excelEngine.Excel.DefaultVersion = ExcelVersion.Excel2016
'Create a workbook with a worksheet
Dim workbook As IWorkbook = excelEngine.Excel.Workbooks.Create(1)
'Access the first worksheet from the workbook instance
Dim worksheet As IWorksheet = workbook.Worksheets(0)
'Insert sample text into cell “A1”
worksheet.Range("A1").Text = "Hello World"
'Save the workbook to disk in xlsx format
workbook.SaveAs("Output.xlsx", ExcelSaveType.SaveAsXLS, Response, ExcelDownloadType.PromptDialog)
End Using
Step 2: Publish the Application to Azure
In the Solution Explorer, right-click on the project name and select Publish.
Publish via Solution Explorer
Or we can go to Build Menu and select Publish myASPApp (your_project_name) to open Publish page.
Publish via Build Menu
Now select the Microsoft Azure App Service, make sure Create New option is selected and then select Publish.
Publish via Microsoft Azure App Service
This opens a Create App Service dialog, where we can add all the necessary resources required to run the application in Azure.
Step 3: Sign in to the Azure account
In the Create App Service dialog, select Add an account, and sign in to the Azure subscription. If you're already signed in, select the account containing the desired subscription from the dropdown.
Step 4: Create a resource group
A resource group is a logical container into which Azure resources like web apps, databases, and storage accounts are deployed and managed.
Next to Resource Group, select New.
Provide a name for the Resource Group and select OK.
Create a resource group
Step 5: Create an App Service plan
An App Service plan specifies the location, size, and features of the web server farm that hosts your app.
Next to App Service Plan, select New.
In the Configure App Service Plan dialog, update the details as per the requirements and Select
Create and configure an App Service Plan
Step 6: Create and publish the web app
In Web App Name, type a unique app name or accept the automatically generated unique name. The URL of the web app is http://<app_name>.azurewebsites.net, where <app_name> is your web app name.
Select Create to start creating the Azure resources.
Create Azure resources
Now the application is being deployed to Azure.
Deploying to Azure
Once the deployment completes, it publishes the ASP.NET web application to Azure, and then launches the app in the default browser.
