AlgoDaily - Working with Spreadsheets in C++

To integrate spreadsheets in algorithmic trading using C++, you can follow these steps:

Include the necessary header files: <iostream>, <fstream>, and <vector>.
Define a function exportSpreadsheetData that takes the filename of the export file and the data to be exported as input.

TEXT/X-C++SRC

1void exportSpreadsheetData(const std::string& filename, const std::vector<std::vector<std::string>>& data) {
2    std::ofstream file(filename);
3
4    if (!file.is_open()) {
5        std::cout << "Failed to open file" << std::endl;
6        return;
7    }
8
9    for (const auto& row : data) {
10        for (const auto& cell : row) {
11            file << cell << ',';
12        }
13        file << std::endl;
14    }
15
16    file.close();
17}

Inside the exportSpreadsheetData function, open the export file using an ofstream object.

TEXT/X-C++SRC

1std::ofstream file(filename);

Check if the file was successfully opened, and handle the error if it fails.

TEXT/X-C++SRC

1if (!file.is_open()) {
2    std::cout << "Failed to open file" << std::endl;
3    return;
4}

Iterate over the data to be exported, and write each cell to the file followed by a delimiter (e.g., comma).

TEXT/X-C++SRC

1for (const auto& row : data) {
2    for (const auto& cell : row) {
3        file << cell << ',';
4    }
5    file << std::endl;
6}

Close the export file.

TEXT/X-C++SRC

1file.close();

In the main function or wherever you want to use the exportSpreadsheetData function, provide the filename and data.

TEXT/X-C++SRC

1std::vector<std::vector<std::string>> data {
2    {"John", "Doe", "john.doe@gmail.com"},
3    {"Jane", "Smith", "jane.smith@gmail.com"},
4    {"Bob", "Johnson", "bob.johnson@gmail.com"}
5};
6
7std::string filename = "data.csv";
8exportSpreadsheetData(filename, data);

Finally, compile and run the program. The spreadsheet data will be exported to the specified file.
