Building a new list is not the best. You can evaluate it directly with 'apply'.
I would also do some other minor tunings, let me suggest this:
(de getJson (Spl File Url Oln)
(when (or Oln (not (info File)))
(wget Url) )
(pipe
(in File
(while (prin (apply echo Spl))
(unless (member "." (prin (trim (till "," "}"))))
(prin ".") ) ) )
(readJson) ) )
Is the 'trim' needed? In any case I see that my last proposal using 'sub?' was
wrong, but I would avoid the 'pack' and use 'member' instead.
Instead of appending ".0", a single dot should suffice, as "123." will be read
as a fixpoint number.
Again, I have not tested - please forgive any errors ;)
