How to Copy Cell Content in Excel in C#

In this tutorial, we delve into the process of copying Excel cell content using IronXL in C#. The video guides viewers through copying single cells, entire rows, columns, and even two-dimensional ranges programmatically. To begin, ensure the IronXL library is installed via the NuGet package manager. The demonstration involves importing the IronXL namespace, which provides access to necessary classes and methods. By using functions like GetColumn and GetRow, viewers learn to copy data from specified cells or ranges and paste it in desired locations within the same worksheet. The tutorial also covers saving the workbook using the SaveAs method, allowing users to verify the results. Key examples include copying cell data from C10 to B13, replicating column A into column H, and duplicating a range from D6 to F8. Finally, viewers are encouraged to explore the software's capabilities by downloading it from the provided link. This comprehensive guide highlights the versatility and power of IronXL in automating Excel file manipulation.

        WorkBook workbook = WorkBook.Load("example.xlsx");

        // Select the first worksheet
        WorkSheet sheet = workbook.WorkSheets.First();

        // Example 1: Copy cell data from C10 to B13
        sheet["B13"].Value = sheet["C10"].Value;

        // Example 2: Copy column A to column H
        for (int row = 0; row < sheet.RowCount; row++)
        {
            sheet[$"H{row + 1}"].Value = sheet[$"A{row + 1}"].Value;
        }

Explanation:

1. Loading the Excel File: The WorkBook.Load method opens an existing Excel file called "example.xlsx".
2. Accessing a Worksheet: It then selects the first worksheet from the loaded workbook for manipulation.
3. Copying Cell Data: The code copies data from cell C10 to B13 directly.
4. Copying a Column: By iterating through each row, column A's content is duplicated into column H.
5. Copying a Range: The nested loop iterates over a two-dimensional range D6 to F8 and copies its content to the range G6 to I8.
6. Saving Changes: Finally, the SaveAs method is used to save the modifications to "modified_example.xlsx".
