- Include the following code snippet in main method of the Program.cs file to set rich text to a single cell in an Excel worksheet.
C#
using (ExcelEngine excelEngine = new ExcelEngine())
{
// Instantiate the Excel application object
IApplication application = excelEngine.Excel;
// Create a new Excel workbook
IWorkbook workbook = application.Workbooks.Create(1);
// Get the first worksheet in the workbook into IWorksheet
IWorksheet worksheet = workbook.Worksheets[0];
// Get a cell in worksheet into IRange and assign text to it
IRange range = worksheet.Range["A1"];
range.Text = "Employee Report";
range.AutofitColumns();
// Initialize RichText for the cell
IRichTextString richText = range.RichText;
// Create and set a new font
IFont blueFont = workbook.CreateFont();
blueFont.Italic = true;
blueFont.RGBColor = Color.Blue;
richText.SetFont(0, 7, blueFont);
// Create and set another new font
IFont redFont = workbook.CreateFont();
redFont.Bold = true;
redFont.RGBColor = Color.Red;
richText.SetFont(9, 14, redFont);
// Save the Excel workbook
workbook.SaveAs("Output.xlsx");
}
VB.NET
Using excelEngine As ExcelEngine = New ExcelEngine()
'Instantiate the Excel application object
Dim application As IApplication = excelEngine.Excel
'Create a new Excel workbook
Dim workbook As IWorkbook = application.Workbooks.Create(1)
'Get the first worksheet in the workbook into IWorksheet
Dim worksheet As IWorksheet = workbook.Worksheets(0)
'Get a cell in worksheet into IRange and assign text to it
Dim range As IRange = worksheet.Range("A1")
range.Text = "Employee Report"
range.AutofitColumns()
'Initialize RichText for the cell
Dim richText As IRichTextString = range.RichText
'Create and set a new font
