Help with creating one excel file with multiple workbooks from multiple excel files using VB.NET

Hi,

If I have the following three excel files: file1.xls, fil2.xls and file3.xls, how do I create file4.xls with three workbooks containing data
from file1.xls, file2.xls and file3.xls?, how do I name the workbooks same names as the filenames?

Thanks,

Victor

is it possible for you to think of using a component like http://www.aspose.com/.net/excel-component.aspx ?

I am also aware (but never used) of this free library: http://excelpackage.codeplex.com/

This code collects the first sheets from several workbooks into a new workbook.
    Sub Merge(result As String, ParamArray sources As String())
        Dim excel = New Microsoft.Office.Interop.Excel.Application
        Dim resultBook = excel.Workbooks.Add
        For Each source In sources
            Dim sourceBook = excel.Workbooks.Open(source)
            Dim sheet As Worksheet = sourceBook.Worksheets(1)
            sheet.Copy(resultBook.Worksheets(1))
            resultBook.Worksheets(1).Name = sourceBook.Name
            sourceBook.Close()
        Next
        resultBook.SaveAs(result, XlFileFormat.xlExcel8)
        resultBook.Close()
    End Sub

Hi,

Thanks for the comments. Regarding the last comment, how do you include the three files in the loop to create one excel file?

Victor
louisfrCommented:
You call that method with the result file name as the result parameter and the three files as the sources parameter:
Merge("C:\MyPath\file4.xls", "C:\MyPath\file1.xls", "C:\MyPath\file2.xls", "C:\MyPath\file3.xls")
