Limitations

GemBox.Spreadsheet Free delivers the same performance and set of features as the Professional version. However, the following limitations are imposed during reading or writing files:

• Maximum number of rows per sheet is 150.
• Maximum number of sheets per workbook is 5.

The SpreadsheetInfo.FreeLimitReached event allows you to control what happens when your application reaches the free version limit. You can use this event to continue using the assembly in Trial mode for performance testing or to stop further reading/writing.

First steps

Using the GemBox.Spreadsheet component is easy and straightforward. After referencing GemBox.Spreadsheet.dll from your project, you can use the following code snippet to generate a simple Excel file:

C# code

static void Main()
{
    // Set license key to use GemBox.Spreadsheet in Free mode.
    SpreadsheetInfo.SetLicense("FREE-LIMITED-KEY");

    // Create a new empty Excel file.
    var workbook = new ExcelFile();

    // Create a new worksheet and set cell A1 value to 'Hello world!'.
    workbook.Worksheets.Add("Sheet 1").Cells["A1"].Value = "Hello world!";

    // Save to XLSX file.
    workbook.Save("Spreadsheet.xlsx");
}

Visual Basic .NET code

Sub Main()
    ' Set license key to use GemBox.Spreadsheet in Free mode.
    SpreadsheetInfo.SetLicense("FREE-LIMITED-KEY")

    ' Create a new empty Excel file.
    Dim workbook = New ExcelFile()

    ' Create a new worksheet and set cell A1 value to 'Hello world!'.
    workbook.Worksheets.Add("Sheet 1").Cells("A1").Value = "Hello world!"

    ' Save to XLSX file.
    workbook.Save("Spreadsheet.xlsx")
End Sub
