Utilities.parseCsv() 'Could not parse text' (Google Apps Script)

Question

I\'m really confused because this was working earlier and I don\'t know why it is broken now. I\'ve got CSV files that I\'m trying to parse. I\'m accessing them using the fo

I tried testing your function slight modified and it looks like it works okay. Here's the one I used. If you can share the data file with us, I'd be glad to take a look at the problem.

function prrrrse() 
{
  var br = '<br />';
  var a = 'test""123,456\n';
  var b = "abc' 'def,ghi\n";
  var h = 'x,y\n';
  var str = h+a+b;
  var delimiter = ',';
  var csv = Utilities.parseCsv(str,delimiter);
  var s = 'str=' + str + br + 'delimiter=' + delimiter + br;
  for(var i = 0;i<csv.length;i++)
  {
    s+='csv[' + i + ']=';
    for(var j=0;j<csv[i].length;j++)
    {
      if(j>0)s+=' , ';
      s+=csv[i][j];
    }
    s+= br;
  }
  dispStatus('Parsing',s, 800, 600); 
}


function dispStatus(title,html,width,height,modal)
{
  var title = typeof(title) !== 'undefined' ? title : 'No Title Provided';
  var width = typeof(width) !== 'undefined' ? width : 400;
  var height = typeof(height) !== 'undefined' ? height : 300;
  var html = typeof(html) !== 'undefined' ? html : '<p>No html provided.</p>';
  var modal = typeof(modal) !== 'undefined' ? modal : false;
  var htmlOutput = HtmlService
     .createHtmlOutput(html)
     .setWidth(width)
     .setHeight(height);
 if(!modal)
 {
   SpreadsheetApp.getUi().showModelessDialog(htmlOutput, title);
 }
 else
 {
   SpreadsheetApp.getUi().showModalDialog(htmlOutput, title);
 }
}

For what it's worth, I just had a similar problem crop up, and after trying to find an errant comma, ended up with a simpler solution. Line 18,000-something (out of 20,000+) in the csv somehow had an extra line break (\n) in it. Eliminating the line break solved the problem.

I was dealing with the same problem today and discovered that trailing spaces at the end of some lines were causing the parser to fail. I resolved this with this regular expression: csvString.replace(/[ \t]+$/gm, '')
