Simple c++ csv writer class.
just c&p or add the CSVWriter.h file to your project.
CSVWriter csv;
csv << "this" << "is" << "a" << "row";
cout << csv << endl;output:
this;is;a;row
CSVWriter csv;
csv.newRow() << "this" << "is" << "the" << "first" << "row";
csv.newRow() << "this" << "is" << "the" << "second" << "row";
cout << csv << endl;output:
this;is;the;first;row
this;is;the;second;row
When each row has a fixed number of colums, CSVWriter can add rows automatically. In this example, each row has 4 colums:
CSVWriter csv;
csv.enableAutoNewRow(5);
csv << "this" << "is" << "the" << "first" << "row" << "this" << "is" << "the" << "second" << "row";
cout << csv << endl;output:
this;is;the;first;row
this;is;the;second;row
CSVWriter csv;
csv.newRow() << "this" << "is" << "the" << "first" << "row";
csv.newRow() << "this" << "is" << "the" << "second" << "row";
csv.writeToFile("foobar.csv");CSVWriter csv;
csv << "append" << "this" << "row" << "please" << ":)";
csv.writeToFile("foobar.csv",true);CSVWriter csv(",");
csv << "this" << "is" << "a" << "row";
cout << csv << endl;
output:
this,is,a,row
CSVWriter csv_a;
CSVWriter csv_b;
csv_a << "this" << "comes" << "from" << "csv_a";
csv_b << "this" << "is" << "from" << "csv_b";
csv_b += csv_a;
cout << csv_b << endl;output:
this;is;from;csv_b
this;comes;from;csv_a
CSVWriter uses a stringstream to serilize values. Each datatype supported by << operator from stringstresm can be used:
char c = 'c';
bool b = false;
short s = 6000;
int i = 300000;
float f = 3.14159;
double d = 4.85875e-270;
string str = "hello world";
char c_str[] = "whats up";
CSVWriter csv;
csv << c << b << s << i << f << d << str << c_str ;
cout << csv;output:
c;0;6000;300000;3.14159;4.85875e-270;hello world;whats up
As you can see, boolean values are serilized to 0 for false and 1 for true.
CSVWriter can escape your seperator
CSVWriter csv;
csv << "escape;me;please";
cout << csv << endl;output:
"escape;me;please"
CSVWriter can also escape quotation marks
CSVWriter csv;
csv << "escape\"me\"please\"\":)";
cout << csv << endl;output:
"escape""me""please"""":)"
