title: How to handle csv mime type on windows machine
body: <p>I am using an angular-file-upload to upload multiple files.I have a filter that allows only csv files to be uploaded. However this filter fails on windows (chrome and firefox) as csv files exported from ms-excel have mime type as "application/vnd.ms-excel" instead of "text/csv". How to handle this so that it works on cross-platorm and across all browsers?</p>
