The following example shows how to create Excel or HTML files by using only the GemBox.Spreadsheet .NET component.
GemBox.Spreadsheet is a C# / VB.NET component that provides a simple and efficient way to read, write, convert, and print native Microsoft Excel (XLSX, XLS) and other spreadsheet (ODS, CSV) formats and various document formats (HTML, PDF, XPS) from .NET applications without the need for Microsoft Excel on either the developer or client machines.
GemBox.Spreadsheet Free is free of charge, while GemBox.Spreadsheet Professional is a commercial version that is licensed per developer.

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. workbook.Save("Workbook.xls");
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. workbook.Save("Workbook.xls")
GemBox.Spreadsheet Free delivers the same performance and set of features as the Professional version. However, the Free version is limited to 150 rows per sheet. You can use the free version for any purpose, including commercial applications.
If you want to see how fast and efficient GemBox.Spreadsheet performs for large files, you can enable Trial mode right from within the free version.
GemBox.Spreadsheet is a standalone .NET component for fast reading, writing, editing, converting and printing of XLSX, XLS, ODS, CSV, HTML, PDF, and XPS files using C# or VB.NET with one simple API.
