csv转json文件

今天因为需要帮一个同事的新闻内容录入为html, 每次手改不方便，所以就弄了个csv(excel)转json的c++程序，然后再利用ejs把它渲染成网页，打开渲染好的网页再保存(不能保存源文件，不然还是空的)，就可以把内容弄成一个html了，此作mark，以下为程序

// convert.cpp
#include <stdio.h>
#include <string>
#include <iostream>
using namespace std;
int main() {freopen("in.csv", "r", stdin);freopen("json.js", "w", stdout);string str, s[50];int g = 0;int status = 0;char ch;str = "";while((ch = cin.get()) != EOF) {str += ch;}for(int i = 0; i < str.size(); i++) {if(status == 0) {if(str[i] == '\"') {status = 1;} else {s[g] += str[i];status = 2;}} else if(status == 1) {if(str[i] == '\"') {if(i + 1 >= str.size()) {g++;break;} else if(str[i + 1] == '\"') {s[g] += '\"';++i;} else if(str[i + 1] == ',') {status = 0;++g;++i;} else if(str[i + 1] == '\n') {status = 0;++g;++i;}} else {s[g] += str[i];}} else if(status == 2) {if(str[i] == ',') {++g;} else if(str[i] == '\n') {++g;} else {s[g] += str[i];}}}int x = 0;puts("var data = [");string name[] = {"title", "detail", "img", "url"};for(int i = 0; i < g; i++) {if(x == 0) {if(i == 0) {puts("\t{");} else {puts("\t},");puts("\t{");}}cout << "\t\t" << name[x] << ": \"" << s[i] << "\"" << (x == 3 ? "" : ",") << endl;x = (x + 1) % 4;}puts("\t}");puts("]");return 0;
}
