I have a Google spreadsheet which I use to track my accounts. I need to add Etsy sales to this, and have added a new sheet which is pasted from the CSV supplied by Etsy.
Unfortunately Etsy only supplies this CSV with dates in US MDY format (e.g. 12/31/2023) but all of the other dates in my spreadsheet are in the more common DMY format (e.g. 31/12/2023). As a result, Sheets does not think that these values are dates (or, in cases where it does think they're dates, it misinterprets them).
How can I get Sheets to recognise these dates and re-format them in a way that makes sense? NB I can't change the locale for the entire spreadsheet, because there are many other colums which contain dates in the correct format.
Alternatively (and slightly less ideally) is there a way I can calculate an intermediate value which Sheets will then recognise as a date? I tried this using a simple Regex (e.g. =REGEXREPLACE(B2, "(\d+)/(\d+)/(\d+)", "$2/$1/$3")) but Sheets still does not recognise the resulting value as a date.
