Creating an Empty Excel Spreadsheet/Workbook Programmatically

The following code snippet exemplifies how to create and save a new Microsoft Excel spreadsheet using C# with the FileFormat.Cells library.

• The code begins by importing the necessary library FileFormat.Cells, providing access to functionalities for Excel spreadsheet manipulation.
• Within the Example namespace, the Program class is defined.
• The Main method serves as the entry point of the program, accepting command-line arguments if any (string[] args).
• An instance of the Workbook class is initialized using Workbook workbook = new Workbook();.
• The Save method is invoked on the workbook instance to save the Excel spreadsheet. The file is saved with the name "Spreadsheet.xlsx" in the root directory `("/") of the disk.

Copy and paste the code snippet below into your main file and execute the program.

 
using System;
using Openize.Cells;

namespace Example
{
    class Program
    {
        static void Main(string[] args)
        {
            // Initialize an instance of the Workbook class.
            var workbook = new Openize.Cells.Workbook();

            // Call the Save method to save the MS Excel Spreadsheet/Workbook onto the disk.
            workbook.Save("Z:\\Downloads\\Spreadsheet.xlsx");
            
            Console.WriteLine("Excel spreadsheet created successfully.");
        }
    }
}

Programmatically insert rows into an Excel worksheet at a specified row index

This C# example showcases how to programmatically insert rows into an Excel worksheet at a specified row index using the Openize.Cells library.

Copy and paste the code snippet below into your main file and execute the program.

 
using System;
using Openize.Cells;

class Program
{
    static void Main(string[] args)
    {
        string filePath = "Z:\\Downloads\\test_spreadsheet.xlsx";

        // Load the workbook from the specified file path
        using (var wb = new Openize.Cells.Workbook(filePath))
        {
            // Access the first worksheet in the workbook
            var firstSheet = wb.Worksheets[0];

            // Define the starting row index and the number of rows to insert
            uint startRowIndex = 5;
            uint numberOfRows = 3;

            // Insert the rows into the worksheet
            firstSheet.InsertRows(startRowIndex, numberOfRows);

            // Get the total row count after insertion
            int rowsCount = firstSheet.GetRowCount();

            // Output the updated row count to the console
            Console.WriteLine("Rows Count=" + rowsCount);

            // Save the workbook to reflect the changes made
            wb.Save(filePath);

            Console.WriteLine("Rows inserted and workbook saved successfully.");
        }
    }
}
