It’s interesting to see the give and take between google sheets and excel. Google sheets came on the scene shooting for total backwards compatibility and then proceeded to develop some really interesting innovations. Now we see new features emerging on both sides that are quickly replicated by the other player. Notably off the top of my mind:

* spill formulas - google first, now supported in MSFT

* # notation - MSFT enhancement to spill formulas not yet adopted in google

* regular expressions - google first, now in Excel

* check boxes - google first, now supported in excel

There must be others. I would expect competitive dynamics where each side tries to build extensions that can’t be replicated on the other side
