Introduction

Microsoft Excel worksheet automation in C# allows developers to generate, edit, and manage Microsoft Excel files automatically by utilizing the power of programming to interface with the Microsoft Excel object model. C# developers may do a wide range of activities, including reading and writing/adding data, formatting cells, making charts, producing reports, and automating Microsoft Office Excel-related actions, by using libraries like Microsoft.Office.Interop.Excel or third-party solutions for automating any unattended, non-interactive client program to run Microsoft Office applications.

Automating Microsoft Excel's new workbook object in C#, Visual Basic, or Microsoft Visual C++ offers a stable and adaptable framework for managing and processing Excel worksheet data with simplicity and precision. It allows developers to design Microsoft Office applications that smoothly incorporate Excel object model functions, carry out data-driven processes, and generate dynamic reports. In this article, we are going to see more about Excel automation in C#.

How to use C# Excel Automation

  1. Create a Visual Studio project.
  2. Install the library IronXL.
  3. Initialize Excel application object interface to automate Microsoft Excel.
  4. Access the worksheet and manipulate data using the object.
  5. Save and close the workbook. Also, release the resource object.

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 make 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);
        // Access the first worksheet in the workbook
        WorkSheet sheet = workbook.CreateWorkSheet("output");
        // Set cell values, var row
        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);
        // Access the first worksheet in the workbook
        WorkSheet sheet = workbook.CreateWorkSheet("output");
        // Set cell values, var row
        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)
		' Access the first worksheet in the workbook
		Dim sheet As WorkSheet = workbook.CreateWorkSheet("output")
		' Set cell values, var row
		sheet ("A1").Value = "Hello"
		sheet ("B1").Value = "World"
		' Save the workbook to a specific file path
		Dim filePath As String = "output.xlsx"
		workbook.SaveAs(filePath)
		Console.WriteLine("File created and saved successfully.")
	End Sub
End Class
VB   C#

This code shows how to automate Excel with IronXL in a simple example:

A new Excel workbook in XLSX format is created by using WorkBook.Create(ExcelFileFormat.XLSX). Getting to a Worksheet: CreateWorkSheet("Sheet1") appends "Sheet1" as a worksheet to the workbook. Sheet ["A1"] and Sheet ["B1"] are where cell values are set value = "Hello", value = "World". Enter values in A1 and B1 correspondingly. Workbook: Preserving its contents. Workbook saves to a given file path when SaveAs(filePath) is used.

Additional Operation

  • Data manipulation: Use different data manipulation techniques, such as filtering, sorting, and cell merging.
  • Graphics and Charts: Utilising Excel data, create graphics and charts.
  • Excel data may be integrated with databases, and it can also be exported to various formats.
