The example below creates an Excel file (in XLS format) with one worksheet and inserts text “Hello world!” into cell “A1”:
var workbook = new ExcelFile();
// Add new worksheet to Excel file.
var worksheet = workbook.Worksheets.Add("New worksheet");
// Set the value of the cell "A1".
worksheet.Cells["A1"].Value = "Hello world!";
// Save Excel file.
Visual Basic .NET code:
Dim workbook = New ExcelFile()
' Add new worksheet to Excel file.
Dim worksheet = workbook.Worksheets.Add("New worksheet")
' Set the value of the cell "A1".
worksheet.Cells("A1").Value = "Hello world!"
' Save Excel file.
