Merge XLTX Files

Introduction

In this tutorial, we will explore how to merge XLTX (Excel Template) files. GroupDocs.Merger is a powerful document manipulation API that enables developers to combine, split, and manipulate various document formats seamlessly within .NET applications. This tutorial specifically focuses on merging XLTX files programmatically.

Prerequisites

Before we begin, ensure you have the following prerequisites set up:

• Development Environment: Install Visual Studio or any .NET-supported IDE.
• GroupDocs.Merger for .NET: Download and install GroupDocs.Merger for .NET from here.
• Sample XLTX Files: Prepare the XLTX files you intend to merge for testing.

Import Namespaces

To get started, include the necessary namespaces in your project:

using System; 
using GroupDocs.Merger;
using System.IO;

Step 1: Initialize Output Directory

Begin by defining the output directory path where the merged XLTX file will be saved.

string outputFolder = "Your_Output_Directory_Path";

Step 2: Set Output File Path

Specify the full path for the merged XLTX file.

string outputFile = Path.Combine(outputFolder, "merged.xltx");

Step 3: Merge XLTX Files

Load the source XLTX files, merge them, and save the result to the specified output file.

// Load the source XLTX file
using (var merger = new GroupDocs.Merger.Merger("Path_To_First_XLTX_File"))
{
    // Add another XLTX file to merge
    merger.Join("Path_To_Second_XLTX_File");
    // Merge XLTX files and save result
    merger.Save(outputFile);
}

Step 4: Handle Output

Finally, display a message confirming the successful completion of the merge operation and specify the location of the merged XLTX file.

Console.WriteLine("\nXLTX files merge completed successfully. \nCheck output in {0}", outputFolder);

Conclusion

In this tutorial, we’ve demonstrated how to use GroupDocs.Merger for .NET to merge XLTX files programmatically. By following these steps, you can efficiently combine Excel template files within your .NET applications.
