Hello Jarno and Leandro - thanks for your question.
Yes - currently that is the process - we are working on automated file transfer solutions, but I do not have a time-frame yet. Connectivity and file management is a big focus this year for Qlik Sense Cloud. We released the SF connector with the launch of QSCB and we are soon releasing the REST connector for QSCB.
One possible solution, in the interim when the REST connector is available - I believe a file placed in dropbox etc. can be read with the REST connector. That way you would automate your upload to dropbox using whatever tools are available - and then schedule the refresh with QSCB where the app is using the REST connector to read the file data. - Just a thought. I'll be playing around with that idea with Qlik Sense Enterprise and I will let you know my findings. HTH
