// Create workbook object | |
Workbook workbook = new Workbook(); | |
// Access the first worksheet | |
Worksheet worksheet = workbook.Worksheets[0]; | |
// Access cells | |

Cell cell2 = worksheet.Cells["B1"]; | |
// Set the styles of both cells to Times New Roman | |
Style styleObject = workbook.CreateStyle(); | |
styleObject.Font.Color = System.Drawing.Color.Red; | |
styleObject.Font.Name = "Times New Roman"; | |
cell1.SetStyle(styleObject); | |
cell2.SetStyle(styleObject); | |
// Put the values inside the cell | |
cell1.PutValue("Hello World!"); | |
cell2.PutValue("Hello World!!"); | |

workbook.Save(dataDir + "SampleOutput_out.xlsx"); |
