How to parse a csv file with d3 when parser is not the comma

I'm working with csv document that I import thanks to d3. Unfortunatelly, the parser is not allways the comma and I didn't find where the parser is recorded in the file architecture... anyway. Now, I know that my parser is a semicolon, then I've tried to use the dsv function like this

var csvfile= d3.dsv(";", VariableWithcsvFileInside);

but console.log(data); return this :

function e(n,e,i){arguments.length<3&&(i=e,e=null);var a=Cn(n,t,null==e?r:u(e),i);return a.row=function(n){return arguments.length?a.response(null==(e=n)?r:u(n)):e},a}

Is there a script that I have to import or something I do wrong? Thanks for anwering.

PS : var csvfile = d3.csv.parse(VariableWithcsvFileInside);works...

Hard to tell what's happening, because you didn't include the code that loads and parses the data from a url, but this is how it should work:

// ssv is "Semicolon Separated Values" parser
var ssv = d3.dsv(";", "text/plain");

// Load and (later, asynchronously) parse the data
ssv(url, function(data) {
  console.log(data); // should log an array of parsed values
});

If the data is already loaded and just needs to be parsed then the 2nd line becomes:

var data = ssv.parse(stringOfDataThatWasAlreadyLoaded);
console.log(data); // should log an array of parsed values
