I ran into this... last year when trying to do something with excel (I forget what excactly, apart from it needing joins and some analysis between several datasets).
It felt so unintuative with the tables "embedded" into sheets, it feels like they should be a sheet or a table, not both.
Power queries seemed a really neat tool for non-coders to munge data as needed.
Would be easier to see on an example.
Btw it's kind of funny seeing so many HN users, many of whom must be working on software that competes with Excel either directly or indirectly, who are so unknowing of the full capabilities of Excel, capabilities that are the bread and butter of any e.g. financial analyst, or logistics manager, or any smart non-programmer white collar worker. Maybe this "hacker repulsion field" is the secret of its dominance -- you can't compete with it if you never learn what it can do.
They're the only reason I actually like to use Excel now. PowerBI has those natively built-in in a more modern iteration but is not as flexible (little direct data entry capability). That said PBI is ultimately meant for reporting.
I've used Google Sheets for years and greatly prefer it over Excel at this point. The killer feature is the sharing, which Excel does not do unless Microsoft 365 has greatly changed. The graphics, pivot tables, and functions are entirely sufficienty for cash flow and revenue models.
Even basic chart types are not supported, I think it might be due to limits of what's possible in the browser.
Granted though, excel can't backed on bigquery.
My point being, don't judge spreadsheets by Google Sheets. Actually use Excel and you'll see a much more capable system and get a better understanding of why people (particularly non-programmers in business settings) stick with it.
EDIT: Pivot tables are in Google Sheets, so either I missed them before or they were added after I last gave it a serious look. My google-fu is not discovering the date they were added.
