Copy Data Within Workbook using Aspose.Cells

Introduction

Managing data within Excel workbooks is a core part of many applications. Imagine you have a template or a sheet filled with essential data, and you want to duplicate it within the same workbook for further use. This is where Aspose.Cells for .NET shines! In this guide, we’ll walk you through copying data within the same workbook, using Aspose.Cells, with a friendly and clear step-by-step tutorial.

Prerequisites

Before we jump into the coding, let’s make sure we have everything we need to complete this task:

1. Aspose.Cells for .NET Library – Download the latest version from Aspose.Cells for .NET download page.
2. Development Environment – You’ll need a .NET-compatible IDE, like Visual Studio.
3. License – Using a free trial or a purchased license for Aspose.Cells. You can get a temporary license here or explore purchase options here.

Import Packages

In your code, you’ll need to import Aspose.Cells to utilize its classes and methods:

using System.IO;
using Aspose.Cells;
using System;

Let’s dive into the code! We’ll break down the task of copying data within a workbook using Aspose.Cells for .NET into easy-to-follow steps.

Step 1: Set Up Your Directory Paths

Before we start handling the workbook, let’s define where our files are located and where we want to save the output. Setting up a directory path keeps things organized.

// Set the directory path for documents.
string dataDir = "Your Document Directory";
string inputPath = dataDir + "book1.xls";

Here, replace "Your Document Directory" with the actual path where your workbook is stored. This path variable will make it easy to refer to your input and output files.

Step 2: Open the Existing Excel File

To work with an Excel file, we need to load it into the workbook object in Aspose.Cells. This step opens the file you want to copy data from.

// Open an existing Excel file.
Workbook wb = new Workbook(inputPath);

With this, our Workbook object wb is now ready to interact with the contents of book1.xls.

Step 3: Access the Worksheets Collection

Now that the workbook is open, we’ll access its collection of worksheets. The WorksheetCollection class helps us work with multiple sheets within the workbook.

// Create a Worksheets object that references all sheets in the workbook.
WorksheetCollection sheets = wb.Worksheets;

Here, sheets will allow us to manipulate each sheet in the workbook, including adding a copy of an existing sheet.

Step 4: Copy Data to a New Sheet

The main part of our task is copying the contents of one sheet to a new sheet within the same workbook. In this example, we’ll copy data from “Sheet1” to a new sheet.

// Copy data from "Sheet1" to a new sheet within the workbook.
sheets.AddCopy("Sheet1");

The AddCopy method creates an exact copy of the specified sheet, appending it to the workbook. Here, we’re duplicating “Sheet1.” You can specify the name of any sheet you’d like to copy.

Step 5: Save the Workbook with the New Sheet

After copying the sheet, save the workbook with a new name or in a new location to preserve the changes.

// Save the workbook with the copied data.
wb.Save(dataDir + "CopyWithinWorkbook_out.xls");

This line saves the modified workbook as CopyWithinWorkbook_out.xls in the specified directory.
