Leave out the first row for headines and fill the rest of the excel with a given List<string[]>?

I have:

            //todo: convertiere objekte in die Tabelle

            ExcelEngine excelEngine = new ExcelEngine();

            IApplication application = excelEngine.Excel;

            application.DefaultVersion = ExcelVersion.Excel2013;

            IWorkbook workbook = application.Workbooks.Create(1);

            IWorksheet worksheet = workbook.Worksheets[0];

            //Import the data to worksheet.
            worksheet.ImportData(_excelObjekt, 2, 1, false);//  "excelObjekt" contains a List<string[]>



But this will return a new empty excel file ...

no, i managed it with a for loop and ""worksheet.ImportData(_excelObjekt, ..., false);//  "excelObjekt" contains a List<string[]> to fill an excel, but he clears out the first row of my excel, but there was some writing in it before, what to do?

Hi Testname,

Thank you for contacting Syncfusion support.

We are able to reproduce the issue. As per XlsIO behaviour, ImportData method imports only the list objects in the specified row and column. We request you to use ImportArray method to import list of string array. Kindly refer the below code example to achieve your requirement and let us know if it helps.

Code Example:

            ExcelEngine excelEngine = new ExcelEngine();

            IApplication application = excelEngine.Excel;

            IWorkbook workbook = application.Workbooks.Create(2);

            IWorksheet worksheet = workbook.Worksheets[0];

            List<string[]> quarters = new List<string[]>();

            string[] quarter1={"Jan","Feb","Mar"};

            string[] quarter2 = { "Apr","May", "Jun" };

            string[] quarter3 = { "jul", "aug","sep" };

            string[] quarter4 = { "oct", "nov", "dec" };





            for (int i = 0; i < quarters.Count; i++)


                worksheet.ImportArray(quarters[i], 2 + i, 1, false);


            workbook.Version = ExcelVersion.Excel2013;
