Hello again, sorry, I’ve looked and tried a few things (you could try some too, maybe it’ll magically work) but unfortunately I get the same error (as I outlined here a few days ago). As said there, this could be a bug; what has finally worked for me somehow was making new files and trying to import the excel file there, and the not-so-great task of making endless changes or new excel files in hopes of it catching on.
Some formatting things: sometimes if cells are right-outlined (you have a few) it doesn’t work, and I would delete/rewrite all left, right cells so that they don’t contain any apostrophes anymore (double check if the left one is actually deleted). Hope you get it figured out and if you do please let me know what did it! Sorry I couldn’t help further.
