    Hi @Rajendra Deshpande ,

    Try using Microsoft.Office.Interop.Excel.

    Check the following steps and code.

    • Add a reference to the Microsoft Office Interop Excel library:
      1. Right-click on your project in the Solution Explorer and select "Add" > "Reference..."
      2. In the Reference Manager, go to "Assemblies" > "Extensions".
      3. Look for "Microsoft.Office.Interop.Excel" and check it. Then click "OK".
    Imports Excel = Microsoft.Office.Interop.Excel
    Public Class Form1
        Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
            ' Create a new instance of Excel application
            Dim excelApp As New Excel.Application
            ' Make the Excel application visible
            excelApp.Visible = True
            ' Add a new workbook
            Dim workbook As Excel.Workbook = excelApp.Workbooks.Add()
            ' Optional: Access the first worksheet
            Dim worksheet As Excel.Worksheet = CType(workbook.Sheets(1), Excel.Worksheet)
            worksheet.Name = "MySheet"
            ' Optional: Write some data to the worksheet
            worksheet.Cells(1, 1).Value = "Hello, Excel!"
        End Sub
    End Class

    Best Regards.

    Hello Rajendra Deshpande,

    Microsoft Excel in Visual Basic .NET is by using the Process class to start Excel as an external application. Here's how you can do it:

    Imports System.Diagnostics

    Public Class Form1

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim excelProcess As Process = New Process()
        ' Specify the path to Excel executable
        excelProcess.StartInfo.FileName = "excel.exe"
        ' Start Excel
    End Sub

    End Class

    In this code:

    We import the System.Diagnostics namespace.

    Inside the button click event handler, we create an instance of the Process class.

    We specify the path to the Excel executable using StartInfo.FileName.

    We start Excel by calling the Start() method of the Process instance.

    This method directly starts Excel as an external application without accessing its object model. It's simpler but doesn't provide direct control over Excel's features like manipulating workbooks and worksheets.
