Add header to object or csv string

Question

I'm using Papaparse with my csv (no header) string to give me an array of objects. I can parse the string without a header then change the keys or I can add a header string to my csv string and then parse that. I haven't had luck with either approach

var csvString = txtArea.value.trim();
var header = 'Header1,Header2,Header3,Header4';
csvString = header+csvString;
var objects = Papa.parse(csvString,{header:true});

Answer 1

You must insert a linebreak \n between header and the CSV :

csvString = header+'\n'+csvString;

Then your code works and produces objects on the form

{ 
   "Header1" : "a",
   "Header2" : "b",
   ..
}
