Let’s get started and unlock the power of Aspose.Cells to make your Excel tasks a breeze!

Prerequisites

Before we jump into the coding part, here’s what you need to have:

  1. Visual Studio: Make sure you have Visual Studio installed on your machine. It’s a powerful IDE that makes working with .NET projects much easier.
  2. Aspose.Cells for .NET: You can download it from here. If you want to test it out first, check out the free trial.
  3. Basic Knowledge of C#: A little familiarity with C# programming will help you understand the examples better. Don’t worry if you’re not an expert; we’ll guide you through the code step by step!

Import Packages

Before we can start coding, we need to import the necessary packages in our C# project. Here’s how to do it:

Create a New Project

  1. Open Visual Studio and create a new project.
  2. Choose Console App (.NET Framework) from the available templates and give your project a name.

Install Aspose.Cells

You can install Aspose.Cells using NuGet Package Manager. Here’s how:

  • Right-click on your project in the Solution Explorer.
  • Select Manage NuGet Packages.
  • In the Browse tab, search for Aspose.Cells.
  • Click Install.
using System.IO;
using Aspose.Cells;

Once you have everything set up, we’re ready to write some code! Now, let’s break down the process into detailed steps. We’ll go through everything from loading an Excel file to saving the modified file.

Step 1: Define the File Path

First, we need to set the path to our Excel file. Here’s how to do it:

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

Replace "Your Document Directory" with the actual path where your Excel file is stored. This is where our sample.xlsx file will be located.

Step 2: Load the Workbook

Next, we’ll load the workbook (Excel file) that we want to work with:

Workbook workbook = new Workbook(dataDir + "sample.xlsx");

This line creates a new Workbook object, allowing us to manipulate the Excel file programmatically. Make sure that sample.xlsx exists in the specified directory, or else you’ll run into an error.

Step 3: Access the Worksheet

Once we have the workbook, we need to access the specific worksheet we want to modify. For simplicity, we’ll work with the first worksheet:

Worksheet worksheet = workbook.Worksheets[0];

Step 4: Group Rows

Now it’s time to group the first six rows together. Grouping rows allows us to collapse or expand them easily:

worksheet.Cells.GroupRows(0, 5, true);

Here, we’re grouping rows 0 through 5 (the first six rows). The true parameter indicates that we want to collapse these rows by default.

Step 5: Group Columns

Just like rows, we can also group columns. We’ll group the first three columns in this step:

worksheet.Cells.GroupColumns(0, 2, true);

This code will group columns 0 through 2 (the first three columns) and also collapse them by default.

Step 6: Set the Summary Column Position

Now that we’ve grouped our rows and columns, let’s specify that we want the summary column to appear on the right:

worksheet.Outline.SummaryColumnRight = true;

This simple line of code is what makes our summary row appear on the right side of our grouped columns.

Step 7: Save the Modified Excel File

After making all the changes, we need to save our workbook. Here’s how you can do that:

workbook.Save(dataDir + "output.xls");

This code saves the modified workbook as output.xls in the specified directory. Make sure to check this file to see your changes!

Conclusion

And there you have it! You’ve successfully created a summary row on the right side of your grouped data in an Excel file using Aspose.Cells for .NET. This method not only helps keep your data organized but also makes it visually appealing and easier to interpret. Whether you’re summarizing sales figures, academic results, or any other dataset, this technique will surely come in handy.
