Error when trying to add Pluto to Julia (Mac)

Does someone know why it can’t find the Excel file, even though I have it downloaded?

Looks like a standard file-not-found error. Since the file address was specified using only its filename itself and not the directory where it’s contained, my first guess would be that it’s not in the same local directory that this Pluto instance is operating from (you can check this with the pwd() function), so it couldn’t be found there.

You can troubleshoot this with isfile(filename) where you replace filename with the address you’re trying to use for the file. You might need to try specifying the absolute filename, e.g. something like "/Users/username/Downloads/filename.xlsx".
