when attempting to drop an excel file in a chat, whether it is xls, xlsx or csv, we get a message it is not a supported type
Be able to accept excel files
Not sure if this applies, but you have to have the MIME type enabled in the File Upload section of the Administration. Multiples are separated by commas. The 2 I use for excel files are:
application/vnd.openxmlformats-officedocument.spreadsheetml.sheet,application/vnd.ms-excel

My complete set of MIME types, which supports: images, audio, video, zip/rar files, pdf, text, word (doc, docx) and excel (xls, xlsx) is as follows:
image/*,audio/*,video/*,application/zip,application/x-rar-compressed,application/pdf,text/plain,application/msword,application/vnd.openxmlformats-officedocument.wordprocessingml.document,application/vnd.openxmlformats-officedocument.wordprocessingml.document,application/vnd.openxmlformats-officedocument.spreadsheetml.sheet,application/msword,application/vnd.ms-excel,text/markdown
This issue has been marked as stale because there has been no further activity in the last 10 days. If the issue remains stale for the next 4 days (a total of two weeks with no activity), then it will be assumed that the question has been resolved and the issue will be automatically closed.
