I don't know if the last null check is necessarily expected behavior. Null is very different than an empty string. An exception for undefined may be desired as well, but I would recommend not replacing null with an empty string. I've testing and found that you are correct.
This seems to work in Chrome and Opera. Safari just opens a page with the content. Internet Explorer For my situation, I'm going to generate my CSV server side and serve it that way, sadly. In Chrome 35 update, download attribute behavior was changed. Monu Monu 4 4 silver badges 2 2 bronze badges. You also can check this one : github. Works perfectly!

Feel free to update or copy if you think it's a better approach. Do you have an example of special characters that break the simple approach of replacing " with ""?
Parsing the CSV is tricky, and should handle line breaks inside quotes, commas in quotes, etc. Serdar Didan Serdar Didan 3 3 silver badges 5 5 bronze badges. Hi Mar This is required for some languages. For example, the Cyrillic alphabet. That window. Wrapping it in setTimeout helps, see here. I wonder how other versions behave.

I'm upvoting this one as the accepted answer for some reason puts everything into a single column. This breaks it all up into separate columns and the JSON like data format support is incredibly useful.
This works when the link is first added to document body and then click is called. And then it is removed from dom. After that, you can write the code to execute when submit event is triggered by the user. Then, you need to create a new instance of FileReader class using the following code:. First, you need to define what happens when the reading operation has been completed with the onload event handler.
The result of the reading operation is passed to the event. The full HTML page code will be as follows:. You will see the CSV content rendered on your browser. You just need to parse this string as an array of objects next. Caveat This solution only handles the case when the data is "simple". If the data might have comma , in it then, in order for the file to work properly we'll have to put the value with the comma in it inside quotes.
This can be added quite easily. However, what happens if the data can also contain quotes? We will then have to escape those. This is not "unsolvable" of course, but it needs some more work and currently I did not have the need for that. Written by Gabor Szabo Published on You can use core javascript code to read a CSV file using regular exp but using papaparse plugin, you get more advanced options to parse the CSV file.
You can also use this library with jquery not mandatory , that makes it easier to select files from the DOM. Papa parser support all modern browsers except IE10 below. You can use this parsed data for further processing like sending to a server or storing in HTML5 local storage.
Step 1: Included papa parse and jQuery files into head section of index. I used HTML5 file input with attributes like validation etc, As you can see file upload input field is a required field and allows to choose CSV formatted file. Step 3: Initialize Papa parse to parse csv file and set config parameters.
