Tried to implement export ng-grid to csv functionality using the ng-grid-csv-export plugin. But it did not work for IE. Next, followed this blog. It uses node.js on server to return csv from webservice, however, we don't have access there.
Then followed this post to implement the form action for IE. However, this does not work as downloadCsv function is not getting called.
Please let me know if I'm missing out on something and request you to please post an example of a URL which accepts a POST request with JSON encoded object in the payload and return a CSV.
