Correction. Excel DOES NOT HAVE PYTHON. Your python is sent to Microsoft's cloud instance of Python and the result there is sent back to your Excel sheet. No actual python is being executed on your machine.
Excel can't import a CSV file reliably though - and neither can any other spreadsheet software I've ever tested. They have problems with dates, numeric values, etc.
The only reliable way to work with CSV is in a programming language of your choice or a plain text editor.
I've never had any issue and have used CSV for years from hundreds of sources. I prefer the "what you see is what you get" and not Excel's "helpful" guessing at dates.
Excel can't even get it's own shit right when it's in XLSX:
It is. So not really that great, imo. Just another rent seeking behavior to force a current subscription.
Don't get me wrong, I'm certain it scratches an itch many people have, just the fact they put it in the cloud is a hell of a lot of needless complexity and antiuser.
Forgive me if I'm wrong, but isn't that something entirely different? This is python in a cell of a spreadsheet, which could be really good, but what you linked seems to be for macros, same as excel's VBA
Do you need to? I feel like learning Python wouldn't give much benefit here, unless you're already using Excel to create applications. In that case, learning Python might let you start making applications that better suit your needs.
Nah I was kind of joking. I do feel like understanding Excel really well has helped me stay ahead of my coworkers, but obviously people who can't figure out Excel won't be figuring out python anytime soon.
That would make some things so much easier, imagine using python string formatting instead of excel CONCAT and '&'... but it's running on the cloud, so going to be slow and fundamentally useless.
