How to create an Excel file in Windows Forms

3 mins read

Syncfusion Essential XlsIO is a .NET Excel library used to create, read, and edit Excel documents. Using this library, you can create an Excel document in Windows Forms.

 

Steps to create an Excel file programmatically:

 

  1. Create a new Windows Forms application project.

 

Create Windows Forms application in Visual Studio

 

  1. Install Syncfusion.XlsIO.WinForms NuGet package as reference to your .NET Framework applications from the NuGet.org.

 

Adding XlsIO reference to the project

 

  1. Include the following namespaces in the Form1.Designer.cs file.

 

using Syncfusion.XlsIO;
using System;
using System.ComponentModel;
using System.Windows.Forms;

 

Imports Syncfusion.XlsIO
Imports System.ComponentModel
Imports System.Windows.Forms

 

  1. Add a new button in Form1.Designer.cs to create Excel file as follows.

 

private Button btnCreate;
private Label label;
 
private void InitializeComponent()
{
  btnCreate = new Button();
  label = new Label();
 
  //Label
  label.Location = new System.Drawing.Point(0, 40);
  label.Size = new System.Drawing.Size(426, 35);
  label.Text = "Click the button to view an Excel spreadsheet generated by Essential XlsIO. Please note that MS Excel Viewer or MS Excel is required to view the resultant document.";
  label.TextAlign = System.Drawing.ContentAlignment.MiddleCenter;
 
  //Button
  btnCreate.Location = new System.Drawing.Point(180, 110);
  btnCreate.Size = new System.Drawing.Size(85, 26);
  btnCreate.Text = "Create Document";
  btnCreate.Click += new EventHandler(btnCreate_Click); 
   
  //Create Spreadsheet
  ClientSize = new System.Drawing.Size(450, 150);
  Controls.Add(label);
  Controls.Add(btnCreate);
  Text = "Create Spreadsheet";
}

 

Private label As Label
Private WithEvents btnCreate As Button
 
Private Sub InitializeComponent()
  label = New Label()
  btnCreate = New Button()
 
  'Label
  label.Location = New Drawing.Point(0, 40)
  label.Size = New Drawing.Size(426, 35)
  label.Text = "Click the button to view an Excel spreadsheet generated by Essential XlsIO. Please note that MS Excel Viewer or MS Excel is required to view the resultant document."
  label.TextAlign = Drawing.ContentAlignment.MiddleCenter
 
  'Button
  btnCreate.Location = New Drawing.Point(180, 110)
  btnCreate.Size = New Drawing.Size(85, 26)
  btnCreate.Text = "Create Document"
 
  'Create Spreadsheet
  ClientSize = New Drawing.Size(450, 150)
  Controls.Add(btnCreate)
  Controls.Add(label)
  Text = "Create Spreadsheet"
End Sub

 

  1. Add the following code in btnCreate_Click to create Excel file with simple text.

 

//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 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");
}

 

'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 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")
 
End Using
