C# EPPlus delete row from excel sheet


I'm currently working with an Excel file that has leading rows that have information I don't need. These extra rows also mess with importing that data in the header row below. So I'm trying to remove them to work with the data.

using (var pack = new ExcelPackage(myFileInfo))
{
    // Should return the sheet name
    var ws = pack.Workbook.Worksheets.FirstOrDefault();
    // Should Delete rows 1-5 and shift up the rows after deletion
    ws.DeleteRow(1,5,true);
}

I was thinking something like the above would work, but I've not had much success with it.

The goal would be to delete rows 1-5, shift up the rest of the data (maybe a merge would work?) then convert it into a datatable.

Anyone have tips or resources on removing rows from my excel sheet (prior to moving it into a datatable since that is where the issue occurs)


Solution

  • The code as you have it will remove the first 5 rows but you also need to do something with the amended file. You could save it in place with:

    pack.Save();
    

    or save to a new location with:

    pack.SaveAs(new FileInfo(outputFilePath));
    

    I have uploaded a complete example here:

    static void Main(string[] args)
    {
        var myFileInfo = new FileInfo("Demo.xlsx");
        using (var pack = new ExcelPackage(myFileInfo))
        {
            var ws = pack.Workbook.Worksheets.FirstOrDefault();
            ws.DeleteRow(1, 5, true);
            pack.SaveAs(new FileInfo("output.xlsx"));
        }
    }
    

    If you build and run the solution you can see that it transforms the demo file from this in the input file (Demo.xlsx):

    input file screengrab

    to this in the output file:

    output file screengrab

    with the first 5 rows removed and everything shifted up.
