Properties:
- RFC-4180 compliant
- STL-friendly interface: streams, iterators, ranges
- Works with any character set (
char,wchar_t, etc) - Header-only: no build required, just include files
- Supports various delimiters and quote characters
- Able to handle named columns
- No external dependencies
- C++11-ready (range-based for and movement semantics) but compiles cleanly with C++03.
- Writing csv files:
#include <fstream>
#include "text/csv/ostream.hpp"
namespace csv = ::text::csv;
// ...
std::ofstream fs("employees.csv");
csv::csv_ostream csvs(fs);
csvs << "name" << "salary" << csv::endl
<< "John" << 10000 << csv::endl
<< "Andy" << 20000 << csv::endl
;- Reading csv files:
#include <fstream>
#include <iostream>
#include <string>
#include "text/csv/istream.hpp"
namespace csv = ::text::csv;
// ...
std::ifstream fs("employees.csv");
csv::csv_istream csvs(fs);
std::string name;
unsigned salary;
std::string header1, header2;
csvs >> header1 >> header2;
while (csvs) {
csvs >> name >> salary;
std::cout << header1 << ": " << name << ", "
<< header2 << ": " << salary << "\n";
}- Using STL algorithms with csv iterators
#include <fstream>
#include <algorithm>
#include "text/csv/iterator.hpp"
namespace csv = ::text::csv;
// ...
typedef csv::input_column_iterator<double> I;
std::vector<double> vec;
std::ifstream fs("numbers.csv");
csv::csv_istream csvs(fs);
// Copy a single row into vector
std::copy(I(csvs), I(), std::back_inserter(vec));The library is licensed under permissive Boost license. See file
