Why? Libreoffice calc had python for years now and nobody cared:

Beacuse anyone with a budget had Excel already - and had to use Excel to be able to use other peoples' spreadsheets. LibreOffice is not bug compatible with Excel.

Look what Excel had tro do to replace Lotus 1-2-3. Including making 1900 a leap year beacuse Lotus had the error.

I love free software as much as anyone, but when I'm forced to use a spreadsheet I'm glad we get office at work. The UI/UX of LibreOffice could use a lot of improvements

Because the world runs Excel, not LibreOffice Calc.

For someone working outside IT but who has coding skills, it's great. My previous work computers have been tightly controlled by IT and installing libreoffice on them wouldn't have been permitted.

I'd be happy if I could just represent integers with more than 15 digits without rounding (e.g. 64-bit primary keys)

64 bit integers can. Excel uses 64 bit floating point. Try the formula

  =1 = (1+1e-16)

and you'll get TRUE.

Here you go: https://blog.adaptiverisk.com/post/2023-08-22-dataslicer/ Calculations are local, not in the cloud.

We're working on this at op (https://opapp.io). Pandas in a spreadsheet, just not an excel spreadsheet if you're able to jump ship.

> it will be amazing and very widely adopted.

The calculations in the cloud?

Why would the vast majority of Excel users even notice or care about this?

The ones that use python would. It being cloud-based makes it a pretty useless feature for anything that I was using Python & Pandas for.

If it was on the client side, I'd be rolling it out to users the moment it was available.

Because they have financial data on it and putting financial information outside computers your company controls is a massive risk.
