We talked with Kris at OOW13 and he mentioned that in version 2.0.4 of the APEX Listener you could upload XLSX files. We installed 2.0.4 today and still cannot upload XLSX files.
Anyone get this to work?
Do we need to be on a more current version of APEX? We are on 4.1.1.
Looks like we will try again with version 2.0.5.
