Excel file type is detected as "bin" about mime HOT 4 CLOSED

Package has been updated.

from mime.

File maybe too small to detect correct filetype.
libmagic just check file headers(signatures) and if no match, returns default type(application/octet-stream with .bin extension)

Hey @hey-red
Thanks for answer,
It is interesting that when opening file in excel and just saving it, then it works.
Also we have other sample files (that we can't share it here because of sensitive data in it) that they have content and are not small, and same thing happens to them, so I doubt it's related to file size

You can try to build your own magic.mgc, because I don't know when I can update .mgc file in that repo(it very old build).
magic.mgc is it compiled libmagic database, that uses these files as source
https://github.com/file/file/tree/master/magic/Magdir
also, maybe you interesting how libmagic detect .xlsx
https://github.com/file/file/blob/master/magic/Magdir/msooxml
