Please Use the below code if you are getting multiple tables from dataset and you should take care of the logic of inserting data tables into excel.

    static void Main(string[] args)
    {
        DataSet ds = new DataSet();

        //Convert the XML into Dataset
        ds.ReadXml(@"E:\movies.xml");

        //Retrieve the table fron Dataset
        //DataTable dt = ds.Tables[0];

        // Create an Excel object
        Microsoft.Office.Interop.Excel.Application excel = new Microsoft.Office.Interop.Excel.Application();

        //Create workbook object
        string str = @"E:\test.xlsx";
        Microsoft.Office.Interop.Excel.Workbook workbook = excel.Workbooks.Open(Filename: str);

        foreach (DataTable tab in ds.Tables)
        {
            FromDataTableToExcel(tab,excel,workbook);
        }

        //Save the workbook
        workbook.Save();

        //Close the Workbook
        workbook.Close();

        // Finally Quit the Application
        ((Microsoft.Office.Interop.Excel._Application)excel).Quit();

    }

    static void FromDataTableToExcel(DataTable dt, Microsoft.Office.Interop.Excel.Application excel, Microsoft.Office.Interop.Excel.Workbook workbook)
    { 
        //Create worksheet object
        Microsoft.Office.Interop.Excel.Worksheet worksheet = workbook.ActiveSheet;

        // Column Headings
        int iColumn = worksheet.UsedRange.Columns.Count-1;
        int iColumn1 = iColumn;
        int iColumn2 = iColumn;

        foreach (DataColumn c in dt.Columns)
        {
            iColumn++;
            excel.Cells[1, iColumn] = c.ColumnName;
        }

        // Row Data
        int iRow = 0;

        foreach (DataRow dr in dt.Rows)
        {
            iRow++;

            // Row's Cell Data                
            foreach (DataColumn c in dt.Columns)
            {
                iColumn1++;
                excel.Cells[iRow + 1, iColumn1] = dr[c.ColumnName];
            }

            iColumn1 = iColumn2;
        }

        ((Microsoft.Office.Interop.Excel._Worksheet)worksheet).Activate();

    }
