function parseCSV(str) {
    var arr = [];
    var quote = false;
    for (var row = col = c = 0; c < str.length; c++) {
        var cc = str[c], nc = str[c+1];
        arr[row] = arr[row] || [];
        arr[row][col] = arr[row][col] || '';
        
        if (cc == '"' && quote && nc == '"') { arr[row][col] += cc; ++c; continue; }
        if (cc == '"') { quote = !quote; continue; }
        if (cc == ',' && !quote) { ++col; continue; }
        if (cc == '\n' && !quote) { ++row; col = 0; continue; }
        
        arr[row][col] += cc;
