Program Code – Can C++ Read Excel File? Techniques for Handling Excel Data

// Necessary include directives
#include <iostream>
#include <fstream>
#include <vector>
#include <string>
#include 'xlnt/xlnt.hpp'  // Assumes the xlnt library is installed

// Function declaration to read Excel file and print content
void readExcelFile(const std::string& fileName) {
    // Create an empty workbook and load .xlsx file
    xlnt::workbook wb;
    wb.load(fileName);

    // Accessing the active worksheet
    auto ws = wb.active_sheet();

    // Iterating over each row and column to read data
    for(auto row : ws.rows(false)) { 
        for(auto cell : row) {
            // Print the cell value
            std::cout << cell.to_string() << '  ';
        }
        std::cout << std::endl; // Newline for each row
    }
}

int main() {
    // File path to the Excel file
    std::string filePath = 'example.xlsx';

    // Calling the function to read and print the Excel file
    readExcelFile(filePath);

    return 0;
}

Code Output:

Each row of data from the Excel file is expected to be printed out, with cell values separated by a tab. Each row is printed on a new line.

Code Explanation:

The code starts by including necessary headers for file I/O and string manipulation, along with the ‘xlnt’ library, which is a C++ library for reading and writing Excel files (mainly the newer xlsx format).

We define a function ‘readExcelFile’ that takes the filename as an argument. Within this function, a workbook object is created and the specified Excel file is loaded into it. We then fetch the active worksheet from the workbook.

We have a nested for-loop construct that iterates over the rows and then the cells within each row. The ‘auto’ keyword is used for type inference, making the code cleaner and the iteration process easier. The loop prints out the value of each cell followed by a tab space (‘ ‘).

Finally, the ‘main’ function is pretty straightforward. It simply specifies the path to an Excel file named ‘example.xlsx’, calls ‘readExcelFile’ function with the path, and returns 0 indicating successful execution.

The beauty of using ‘xlnt’ is that it abstracts away the complexities of Excel file formats and allows efficient performance with minimal code for common tasks such as reading files, accessing sheets, and iterating over cells. The library is modern C++ (C++11 and later), making use of features like automatic type deduction and the standard template library (STL) which contribute to its ease of use and performance.
