Copy Worksheet from One Workbook to Another using Aspose.Cells

Introduction

Need a way to efficiently transfer data from one Excel workbook to another in your .NET application? Copying a worksheet from one workbook to another can be incredibly useful, whether you’re managing reports, generating templates, or organizing data on-the-fly. Fortunately, with Aspose.Cells for .NET, this process is straightforward and powerful. In this tutorial, we’ll explore how to seamlessly copy a worksheet from one workbook to another, giving you complete control over data management. In this article, we’ll cover everything you need to know to get started. From setting up Aspose.Cells for .NET in your project to a comprehensive step-by-step guide, you’ll gain the skills to implement this feature smoothly.

Prerequisites

Before diving in, let’s make sure you’re set up with all the necessary tools:

1. Aspose.Cells for .NET Library: This library is essential for working with Excel files in .NET. You can download it here.
2. Visual Studio: We’ll use Visual Studio (or a similar IDE) to write and run the .NET code.
3. Aspose License: If you want to avoid evaluation limitations, consider applying for a free trial or a temporary license.

Import Packages

To get started, import the necessary namespaces into your project:

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

These namespaces will provide access to classes needed for creating, editing, and manipulating Excel workbooks and worksheets. In this guide, we’ll break down each part of the process into clear, manageable steps. Let’s jump into each step!

Step 1: Set the Directory Path

Before creating and saving files, define the directory where you’ll store your workbooks. This will make it easy to access the files later.

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

The dataDir variable stores the path to the directory. Make sure to replace "Your Document Directory" with your actual directory path.

Step 2: Create the First Workbook and Worksheet

Now, let’s create a new workbook with a single worksheet and add some data to it.

// Create a new Workbook.
Workbook excelWorkbook0 = new Workbook();
// Access the first worksheet in the workbook.
Worksheet ws0 = excelWorkbook0.Worksheets[0];

Here, we create a workbook object excelWorkbook0 and retrieve the first worksheet ws0 for data manipulation.

Step 3: Add Header Data to the Worksheet

Let’s populate the first worksheet with header rows. This data will serve as a sample to demonstrate the copying process.

// Populate header rows (A1:A4).
for (int i = 0; i < 5; i++)
{
    ws0.Cells[i, 0].PutValue($"Header Row {i}");
}

Using a loop, we fill the first five rows in column A with header labels. This makes it clear where each new section begins in the worksheet.

Step 4: Populate Detail Data Rows

Next, let’s add some detailed data to give context to our worksheet. This is particularly useful for simulating a report or data analysis sheet.

// Populate detail rows (A5:A999).
for (int i = 5; i < 1000; i++)
{
    ws0.Cells[i, 0].PutValue($"Detail Row {i}");
}

This loop fills rows from A5 to A999 with a simple message, mimicking detailed content commonly found in spreadsheets.

Step 5: Configure Page Setup for Printing

Aspose.Cells allows us to define print settings for the worksheet. Here, we’ll set the top five rows to repeat on every printed page, which is particularly useful for reports.

// Configure page setup to repeat header rows on each page.
PageSetup pagesetup = ws0.PageSetup;
pagesetup.PrintTitleRows = "$1:$5";

By setting PrintTitleRows to $1:$5, we ensure that the first five rows (our headers) will be printed on each page. This feature is ideal for maintaining context when printing large datasets.

Step 6: Create the Second Workbook

Now, let’s create a second workbook where we’ll paste the copied worksheet. This workbook will serve as the destination for our worksheet transfer.

// Create another Workbook.
Workbook excelWorkbook1 = new Workbook();
// Access the first worksheet in the workbook.
Worksheet ws1 = excelWorkbook1.Worksheets[0];

Here, we initialize excelWorkbook1 as our destination workbook and retrieve its first worksheet, ws1, where we’ll paste the copied content.

Step 7: Name the Destination Worksheet

To make it easier to identify, let’s rename the first worksheet in the second workbook.

// Rename the worksheet.
ws1.Name = "MySheet";

Renaming ws1 to "MySheet" makes it simple to distinguish the worksheet in the new workbook, especially when dealing with multiple sheets.

Step 8: Copy Data from the Source Worksheet

Now for the main event: copying the worksheet data from the first workbook to the second one. Aspose.Cells simplifies this with the Copy method.

// Copy data from the first worksheet in the first workbook into the first worksheet of the second workbook.
ws1.Copy(ws0);

The Copy method transfers all the content and formatting from ws0 to ws1. This method is efficient, handling all data in one command.

Step 9: Save the Final Workbook

Once everything is set, save the destination workbook to the specified directory.

// Save the second workbook.
excelWorkbook1.Save(dataDir + "CopyWorksheetFromWorkbookToOther_out.xls");

The Save method saves excelWorkbook1 as an Excel file in your specified directory. The filename here is "CopyWorksheetFromWorkbookToOther_out.xls".
