Excel Automation Using IronXL

An example illustrating the use of IronXL in C# for simple Excel automation can be seen below. Here's an example of how to create a new Excel file, fill in the cells, then save the workbook.

using IronXL;

class Program
{
    static void Main(string[] args)
    {
        // Create a new Excel workbook
        WorkBook workbook = WorkBook.Create(ExcelFileFormat.XLSX);

        // Create a new worksheet in the workbook
        WorkSheet sheet = workbook.CreateWorkSheet("output");

        // Set values in cells
        sheet["A1"].Value = "Hello";
        sheet["B1"].Value = "World";

        // Save the workbook to a specific file path
        string filePath = @"output.xlsx";
        workbook.SaveAs(filePath);

        Console.WriteLine("File created and saved successfully.");
    }
}

using IronXL;

class Program
{
    static void Main(string[] args)
    {
        // Create a new Excel workbook
        WorkBook workbook = WorkBook.Create(ExcelFileFormat.XLSX);

        // Create a new worksheet in the workbook
        WorkSheet sheet = workbook.CreateWorkSheet("output");

        // Set values in cells
        sheet["A1"].Value = "Hello";
        sheet["B1"].Value = "World";

        // Save the workbook to a specific file path
        string filePath = @"output.xlsx";
        workbook.SaveAs(filePath);

        Console.WriteLine("File created and saved successfully.");
    }
}

Imports IronXL

Friend Class Program
	Shared Sub Main(ByVal args() As String)
		' Create a new Excel workbook
		Dim workbook As WorkBook = WorkBook.Create(ExcelFileFormat.XLSX)
