CSV files have wrong type

CSV files should have a content-type of text/csv (https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types/Common_types).

Instead when they are added to uppy and when the request is sent they are treated as type: application/vnd.ms-excel which is wrong. This happens on your online samples too

hi @arturi @goto-bus-stop we have the issues on windows machines…after you mentioned it could be browser related I had a look around and there is actually an open issue with chromium about this: basically they do not have a default mapping for the csv files and that defaults to whatever mapping the os has (which in windows gets the excel type application/vnd.ms-excel). FF has a similar implementation and the result is the same. So basically it is a browser issue when using it on Windows with Excel installed

To double check that I tried with chrome on a macOs and the mime-type is correctly set to text/csv. I am closing the issue, thanks for your time

We use it if the browser hasn’t detected a mime type: https://github.com/transloadit/uppy/blob/58f996c0e481a8ad7932ebd1d544dd730986d973/packages/%40uppy/utils/src/getFileType.js#L8-L14
