javascript - Uploading And Reading CSV-Parse File -

i trying read csv file multiple same colums using node csv-parser

 'from' ' 'to' 'from' ' 'to' 'from' ' 'to'  'germ' ' 'nl' 'turk' ' 'us' 'nile' ' 'br'  'germ' ' 'nl' 'turk' ' 'us' 'nile' ' 'br'  'germ' ' 'nl' 'turk' ' 'us' 'nile' ' 'br'  'germ' ' 'nl' 'turk' ' 'us' 'nile' ' 'br' 

and below code:

req.file('ratefile').upload(function (err, uploadedfile) {         if (err) return responseservice.json(500, err, 'uploaded failed');          console.log(uploadedfile.length) //          if (uploadedfile.length) {             rs = fs.createreadstream(uploadedfile[0].fd);             parser = parse({columns: true, trim: true}, function (err, data){                 var record = {};                 console.log(data);                 _.foreach(data, function(datum, index){                     var routename = datum['from'] +"-"+ datum['to'];                     console.log(routename);                     record.name = datum['from'] +"-"+ datum['to'];                     record.to = datum['to'];                     record.from = datum['from'];                 });                  return responseservice.json(200, res, 'file uploaded');             });             rs.pipe(parser);         } else {             return responseservice.json(500, res, 'please upload file')         }     }); 

and when run that, last column on csv file.

  'from' ' 'to'   'nile' ' 'br'   'nile' ' 'br'   'nile' ' 'br' 

any appreciated. thanks

it parse like

{   "from": "germ",   "to"  : "nl",   "from": "turk",   "to"  : "us",   ... } 

and of course it's not valid json, @ duplicate keys. last key value pair overriding previous pair.

in line

parser = parse({columns: true, trim: true}, function (err, data){ 

use function, or null columns value, like

parse({columns: null, trim: true} 

and print out parsed result, , modify own needs. can use function, don't pretty sure function can solve problems, since still parsing single csv line single object.
