With it, you can automate tasks like creating new worksheets, formatting cells, and even copying rows seamlessly. Imagine handling large datasets or repeating template rows effortlessly—Aspose.Cells for .NET makes these tasks a breeze! In this tutorial, we’ll focus on one specific task: copying rows within an Excel file. We’ll cover the prerequisites, importing necessary packages, and a step-by-step guide to make this process easy. So, let’s dive in!

Prerequisites

Before we jump into the code, here’s what you’ll need:

  1. Aspose.Cells for .NET: Make sure you have the latest version. You can download it here or get a free trial.
  2. Development Environment: Any .NET-compatible environment like Visual Studio.
  3. Basic Knowledge of C#: While this guide is beginner-friendly, familiarity with C# will help you understand each step better.
  4. License: For full access, get a temporary license if needed.

Import Packages

To start, make sure to import the necessary namespaces in your code. These libraries will give you access to the classes and methods needed to handle Excel files.

Let’s break down the code into simple steps. Each step will guide you through the process, from opening an Excel workbook to saving the updated file with the copied rows.

Step 1: Set the Path to Your Directory

First things first, we need to set the directory path where your Excel files are located. Think of this as setting up the workspace so the program knows where to find the files to work on.

// The path to the documents directory.
string dataDir = "Your Document Directory";

Replace "Your Document Directory" with the actual path on your machine where your Excel file (book1.xls) is stored.

Step 2: Open the Existing Excel File

Now that the path is set, let’s load the Excel file into our program. Using the Workbook class from Aspose.Cells, we can easily open and access our Excel file.

// Open the existing Excel file.
Workbook excelWorkbook1 = new Workbook(dataDir + "book1.xls");

Here, excelWorkbook1 is your workbook object that now contains all the data from book1.xls. This allows us to work with worksheets, cells, and rows within this file.

Step 3: Access the Desired Worksheet

With the workbook open, the next step is to select the worksheet where you want to perform the row copy. In this example, we’ll be working with the first worksheet in the workbook.

// Get the first worksheet in the workbook.
Worksheet wsTemplate = excelWorkbook1.Worksheets[0];

The Worksheets[0] index selects the first worksheet. If your data is on a different worksheet, adjust the index accordingly.

Step 4: Copy the Target Row

Now comes the core part of our tutorial: copying a row. Here, we’ll copy the data from row 2 (index 1, since rows are zero-indexed) to row 16 (index 15) within the same worksheet.

// Copy the second row with data, formattings, images, and drawing objects to the 16th row.
wsTemplate.Cells.CopyRow(wsTemplate.Cells, 1, 15);

In this command:

  • Source Row (1): This is the row we’re copying, which corresponds to row 2 in Excel.
  • Destination Row (15): This is where we want the copied row to be pasted, corresponding to row 16 in Excel. The CopyRow method is efficient—it not only copies data but also any formatting, images, or objects in that row.

Step 5: Save the Updated Excel File

Once the row copy is complete, it’s time to save the modified Excel file. This ensures that all changes made to excelWorkbook1 are preserved.

// Save the Excel file.
excelWorkbook1.Save(dataDir + "output.xls");

Here, we’re saving the updated workbook as output.xls in the same directory as the original file. You can change the file name and location if needed.
