csv.js

function parseCSV(data, separator) {
    const lines = data.split(/\r\n|\n/);
    const header = lines[0].split(separator);
    const result = [];

    for(let i = 1; i < lines.length; i++){
        const fields = lines[i].split(separator);
        const line = {};
        for(let k = 0; k < header.length; k++)
            line[header[k]] = fields[k];
        result.push(line);
    }
    return result;
}

/*
var data = "a;b;c;d;e;f;\r\n1;2;3;4;5;6;\r\n1;2;5;6;7;8;\r\n0;;1;;2;;3;";
var result = parseCSV(data,";");
console.log(result);

Result should be an array with 3 items, each item is a named object:
0: {a: "1", b: "2", c: "3", d: "4", e: "5", …}
1: {a: "1", b: "2", c: "5", d: "6", e: "7", …}
2: {a: "0", b: "", c: "1", d: "", e: "2", …}
