Guide to Merging XLSM Files

Introduction

In this tutorial, we’ll explore how to merge XLSM (Excel Macro-Enabled Workbook) files. GroupDocs.Merger is a powerful library that allows developers to manipulate document formats, including merging, splitting, and modifying files programmatically.

Prerequisites

Before you begin, ensure you have the following:

• GroupDocs.Merger for .NET: Download and install the library from here.
• Development Environment: Setup Visual Studio or any compatible .NET development environment.
• XLSM Files: Prepare the XLSM files you want to merge.

Import Namespaces

First, include the necessary namespaces in your .NET project:

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

Step 1: Define Output Folder and File Name

Begin by defining the output folder and the name of the merged XLSM file:

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

Step 2: Load and Merge XLSM Files

Next, load the source XLSM files and merge them into a single file:

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

Step 3: Check Merge Completion

Finally, notify the user about the successful merge completion and display the output path:

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

Conclusion

You’ve learned how to merge XLSM files programmatically. This library simplifies document manipulation tasks, enabling efficient file merging within your .NET applications.
