OpenCSV

Simple CSV library written in C++

It supports custom delimiters and quoting fields

• Writing a file
• Custom delimiter
• Reading a file

Building

Run cmake --build . your root folder and it will generate a file named libcsv.a

Usage example

Writing a CSV file

#include "csv.h"

int main() {
  ocsv::CSV c("myfile.csv");
  c.PushHeader("name");
  c.PushHeader("job");

  c.PushLine("gabriel,programmer");
  c.PushLine("rachell,physician");
  c.Write();
  
  return 0;
}

The output file after writing

name,job
gabriel,programmer
rachell,physician

Custom delimiter

There is a second constructor that takes a second parater which is the delimiter character

// CSV(std::string file, const char &delimiter)
ocsv::CSV c("myfile.csv", ';');

Reading from CSV file

#include <iostream>

#include "csv.h"

int main() {
  ocsv::CSV c("myfile.csv");
  c.Read();
  for (auto &h : c.GetHeaders())
    std::cout << h << "\t";
  std::cout << "\n";

  for (auto &ln : c.GetLines()) {
    for (auto &col : c.GetLine(ln))
      std::cout << col << "\t";
    std::cout << "\n";
  }

  return 0;
}

The output will be

name	job
gabriel	programmer
rachell	physician
