thank! works in chrome, but not in internet explorer (my version is ie 11).

Sorry, I tried to execute this code from Internet Explorer 11. Its not working. Can you please make it work in IE 11??? Waiting for your response

Thank you. This is working well but only for the first page of a table - just the visible view.
Is there a way to tweak this to export the entire table?

@Raverito, @AShakthivel check out my fork https://gist.github.com/kalebdf/ee7a5e7f44416b2116c0/revisions#diff-eacf331f0ffc35d4b482f1d15a887d3bR135
Do a check for IE window.navigator.msSaveOrOpenBlob and then use the Blob object for IE.

Kalebdf,
I used your forked code, and it worked perfectly on my Windows machines with Chrome, IE 11, FireFox and Edge browsers.
Thanks very much.

Thank you!

Hi guys,
i have a question, if someone can help me.

I did a the feature that downloads a csv file with javascript in my application.
It works good till 5000 rows circa, after that when i try to download the file the browser gives me a "Connection Error" .. but actually it isn't a network error because i have already ALL the data before to make the CSV string.

Thanks in advance,

Nico

Very nice thank you, for my usage I needed to add the following to grabCol to handle non-breaking spaces:
if($text=="\xa0") { $text = ''; }
