Combine Multiple Workbooks into a Single Workbook with C++

Sometimes, you need to combine workbooks with various content like images, charts, and data into a single workbook. Aspose.Cells supports this feature. This article shows how to create a console application in Visual Studio and combine workbooks with a few simple lines of code using Aspose.Cells.

Combining Workbooks with Images and Charts

The example code combines two workbooks into a single workbook using Aspose.Cells. The code loads the source workbooks, uses the Workbook::Combine() method to combine them, and saves the output workbook.

Source Workbooks

• charts.xlsx
• picture.xlsx

Output Workbooks

• combined.xlsx

Screenshots

Below are screenshots of the source and output workbooks.

You can use any source workbooks. These images are just for illustration purposes.

The first worksheet of the charts workbook – stacked

The second worksheet of the charts workbook – line

The first worksheet of the picture workbook – picture

All three worksheets in the combined workbook – stacked, line, picture

#include <iostream>
#include "Aspose.Cells.h"
using namespace Aspose::Cells;

int main()
{
    Aspose::Cells::Startup();

    // For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-C

    // Source directory path
    U16String srcDir(u"..\\Data\\01_SourceDirectory\\");

    // Path of the first source Excel file
    U16String sourceFile1 = srcDir + u"SampleChart.xlsx";
    
    // Path of the second source Excel file
    U16String sourceFile2 = srcDir + u"SampleImage.xlsx";

    // Open the first Excel file.
    Workbook sourceBook1(sourceFile1);

    // Open the second Excel file.
    Workbook sourceBook2(sourceFile2);

    // Combine the two workbooks
    sourceBook1.Combine(sourceBook2);

    // Define the output file path
    U16String outputFilePath = srcDir + u"Combined.out.xlsx";

    // Save the target workbook file.
    sourceBook1.Save(outputFilePath);

    std::cout << "Workbooks combined and saved successfully!" << std::endl;

    Aspose::Cells::Cleanup();
}
