What if you have an excel workbook that relies on a bunch of custom formulas. I would be upset if this happened in my workplace. Datasets have been far easier to handle with lambda, vstack, byrow, and the rest. I would not like this move and would have to remain a holdout. That would also frustrate me because of the division.
Are we gonna accept being forever locked in to Microsoft because of custom Excel workbook formulas? Forever paying Microsoft a license fee, because we don't want to covert said formulas or invest in open source software to make it reach parity with Excel.
The problem with this is that the decisionmakers fucked up 10-20 years ago, and now when those decisions are being righted, some poor public servant is paying the price.
