Oh I see! My bad to try to upload a CSV file 
…
Oh no, please… I (and probably others?) have difficulty enough writing times, callsigns etc. onto paper with a pen or pencil while conducting a QSO - the very idea of battling with a smartphone virtual keyboard to do it sends me into a cold sweat of terror! It’s simply not on!!!
But I also see that the user is required to write some kind of file in a text editor, and remember which field goes where in a record. Since I’m far too disorganized to figure out which field goes where, I still have to say I prefer to use my own, user-friendly, online “app” where little thought is required, I just fill in the form from my paper log entries, and everything is managed for me automagically. Also - even if the browser or PC crashes, the app remembers all my inputs up to that moment, so when I start the app in the browser again, it asks me whether I want to populate the table with my previous entries: that’s user-friendliness in action. When I’m finished, I press a button and a SOTA CSV file is created. Easy-peasy, lemon-squeezy, or YMMV…
Of course, there’s also the very fine PC program from Stewart G0LGS for those who wish to do stuff offline.
