Array functions feel like they're just too far from the excel design thinking. A single function that affects nearby cells is hard for me to swallow.

I kind of wish they went for the matlab cell array style where a function can return an array, but it just becomes a data structured stored within a single cell.

So TEXTSPLIT (which is great, finally), would return an object like ARRAY("I", "SAW","A","CAT") and if you wanted to unpack it you could drag a formula that was something like =$A$1?0, =$A$1?1, =$A$1?2, etc.

Or maybe just one single black magic affects-nearby-cells function called "UNPACK"

20 years overdue...

Another one that is massively overdue: take multiple arrays as arguments and return the distinct values, sorted (kind of like the remove duplicate button, but that doesn't require to click a button). [edit] actually it was introduced in 2021 ("UNIQUE" function)

Also take multiple arrays and returns the values that are in common (like an inner join). Use case: you want to align two time series by creating a 3rd time series made of the dates common to both original time series.

Then you can have all sort of finance related function. Validate the checksum for an ISIN, CUSIP, SEDOL, etc.

Excel should also come with the most common holiday list (all the major cities at least).

It’s 2022 and how come they don’t have GPT4 and some stable diffusion built in?

seriously though, I think a copilot-like ML to improve flash fill is a genuinely amazing idea which could save insane hours, especially with people less familiar with complex formulas/coding
