Active with known workarounds but no fix.
A) Manually add the .csv extension to the downloaded file.
B) Use a different browser like Mozilla Firefox or Internet Explorer. The file downloaded using Firefox or Internet Explorer can give the following message “The file you are trying to open, ‘download.xls’, is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now ?”. The file can still be opened by selecting ‘Yes’.
