    Hi sidyusuf ,

    that's possible, but while implement the code logic then only we can give some what better solution, I already done the same stuff in my previous project, but i don't have that part of code at present.

    Request you to refer below link this might be helpful to you.

    Not sure if I have understood you correctly, do you mean that you want to copy one excel document to another for example, File 1 to another File1, with different headers but same contents? If this is the case, then you can refer to following codes:
    Workbook workbook = new Workbook();
    workbook.LoadFromFile(Path of File 1);
    Worksheet worksheet = workbook.Worksheets[0];

    Workbook workbook2 = new Workbook();
    workbook2.LoadFromFile(Path of another File1);
    Worksheet worksheet2 = workbook2.Worksheets[0];

    int i = 2;
    int colunmCount = worksheet.Columns.Count();
    foreach (CellRange range in worksheet.Columns[0])
    CellRange sourceRange = worksheet.Range[1, 1, range.Row, colunmCount];
    CellRange destRange = worksheet2.Range[i, 1, i, colunmCount];
    worksheet.Copy(sourceRange, destRange, true);

    workbook2.SaveToFile("another File1", ExcelVersion.Version2010);
    System.Diagnostics.Process.Start("another File1");
    This solution was based on a free .net excel library( which I often used to manipulate excel files like create, edit, convert, copy etc. You could give a try.

    So you want to copy data from one excel sheet to another right ?
    You need to use EXCEL automation for it, I have a below snippet to copy data from one excel to another
    see below
    public void CopyRanges()
    // only one instance of excel
    Excel.Application excelApplication = new Excel.Application();

    srcPath="C:\\Documents and Settings\\HARRY\\Desktop\\incident.csv";
    Excel.Workbook srcworkBook = excelApplication.Workbooks.Open(srcPath);
    Excel.Worksheet srcworkSheet = srcworkBook.Worksheets.get_Item(1);

    destPath = "C:\\Documents and Settings\\HARRY\\Desktop\\FIXED Aging incident Report.xls";
    Excel.Workbook destworkBook = excelApplication.Workbooks.Open(destPath,0,false);
    Excel.Worksheet destworkSheet = destworkBook.Worksheets.get_Item(1);

    Excel.Range from = srcworkSheet.Range("C1:C100");
    Excel.Range to = destworkSheet.Range("C1:C100");

    // if you use 2 instances of excel, this will not work

    destworkBook.SaveAs("C:\\Documents and Settings\\HARRY\\Desktop\\FIXED Aging incident Report " + DateTime.Now.ToString("MM_dd_yyyy") + ".xls");
    srcxlApp.Application.DisplayAlerts = false;
    destxlApp.Application.DisplayAlerts = false;
    destworkBook.Close(true, null, null);
    srcworkBook.Close(false, null, null);
