This is very simple csv parser project.
#include "CSVParser.h" // include header
int main() {
// csv file path. It doesn't have to be a csv file.
std::string s = "C:\\Users\\CYS\\Downloads\\11.csv";
CSVParser parser; // Create parser
parser.SetColumnsWidth(15); // One column's width, mininum 10
parser.ReadFile(s); // parser.ReadFile(s, '@'); default is `,`
}
