Saving an Excel File with IronXL in VB.NET

You can follow these steps to save an Excel file using IronXL in a VB.NET application. Here is an example code snippet that demonstrates how to use IronXL in VB.NET to save an Excel document:

Imports IronXL
Module Program
    Sub Main(args As String())
        Dim excelFilePath As String = "file path here"
        ' Create a new Excel workbook
        Dim workbook As WorkBook = WorkBook.Create(ExcelFileFormat.XLSX)
        ' Add data or perform operations within the workbook (optional)
        Dim worksheet As WorkSheet = workbook.CreateWorkSheet("Sheet1")
        worksheet("A1").Value = "Hello"
        worksheet("B1").Value = "IronXL!"
        ' Save the Excel workbook to the specified path
        workbook.SaveAs(excelFilePath)
        Console.WriteLine("Excel file saved successfully at: " & excelFilePath)
    End Sub
End Module
Imports IronXL
Module Program
    Sub Main(args As String())
        Dim excelFilePath As String = "file path here"
        ' Create a new Excel workbook
        Dim workbook As WorkBook = WorkBook.Create(ExcelFileFormat.XLSX)
        ' Add data or perform operations within the workbook (optional)
        Dim worksheet As WorkSheet = workbook.CreateWorkSheet("Sheet1")
        worksheet("A1").Value = "Hello"
        worksheet("B1").Value = "IronXL!"
        ' Save the Excel workbook to the specified path
        workbook.SaveAs(excelFilePath)
        Console.WriteLine("Excel file saved successfully at: " & excelFilePath)
    End Sub
End Module
VB.NET

To save an Excel document, replace "file path here" with the appropriate location and filename. You can modify the data or perform other operations within the workbook before saving.

This code snippet creates a new Excel workbook, adds a worksheet named "Sheet1", uses IronXL to write data into cells A1 and B1, and saves the workbook in the XLSX format at the specified file path. Ensure that the location where you plan to save the Excel file has the necessary write permissions. You can also use an existing template Excel file to save the documents.

By running this code, you will be able to use IronXL in a VB.NET program to create an Excel sheet in the specified file directory with the desired data and structure. Make any necessary adjustments to the workbook's data and settings before saving it in the XLSX file format.
