I have tried the below simple importxml formula in a cell
=importxml("https://en.wikipedia.org/wiki/List_of_T_postal_codes_of_Canada", "//td")
But this always returns a "formula parse error" message.
I don't get it, this example is soo simple. It should work fine.
I would make the assumption that you are from Canada. Canada (French) locale uses ;
instead of ,
so most likely it has to do with the spreadsheet locale.
Replace ,
with ;
:
=importxml("https://en.wikipedia.org/wiki/List_of_T_postal_codes_of_Canada"; "//td")
Another solution would be to change the locale settings, please read more here on how to do that.
