var sheet = book.Worksheets[0];
// access CellsCollection of first worksheet
var cells = sheet.Cells;
// write HelloWorld to cells A1
cells["A1"].Value = "Hello World";
// save spreadsheet to disc
book.Save("output.xlsx", SaveFormat.Xlsx);

Use C# to Create an Excel Line Chart

var workbook = new Aspose.Cells.Workbook();

// add a new worksheet to the Excel object
int sheetIndex = workbook.Worksheets.Add();

// obtain the reference of the newly added worksheet by passing its sheet index
Worksheet worksheet = workbook.Worksheets[sheetIndex];

// add sample values to cells
worksheet.Cells["A1"].PutValue(50);
worksheet.Cells["A2"].PutValue(100);
worksheet.Cells["A3"].PutValue(150);
worksheet.Cells["B1"].PutValue(4);
worksheet.Cells["B2"].PutValue(20);
worksheet.Cells["B3"].PutValue(50);

// add a chart to the worksheet
int chartIndex = worksheet.Charts.Add(Aspose.Cells.Charts.ChartType.Line, 5, 0, 15, 5);

// access the instance of the newly added chart
var chart = worksheet.Charts[chartIndex];

// add chart data source from "A1" to "B3"
chart.NSeries.Add("A1:B3", true);

// save the Excel file
workbook.Save( dir + "output.xls");
