Makes no difference that I could tell. I ^C'ed it after about 30
seconds in both cases.

Much faster!

:g/.*name":"\([^"]*\)".*card":"\([^"]*\)".*/let
s=substitute(getline('.'),
'.*stamp":"\(\d\+\)-\(\d\+\)-\(\d\+\).*','\1\2\3','').'.txt'|s//\1,\2/|call
writefile([getline('.')], s, 'a')


runs in about the same time as the "echo" version or the "append it
to a list" version (i.e., one second or less).
