First, do not add quotation marks to it.  They just get in the way.

If you've got an input stream with one element per line that you want
to import into a bash array, you use the "mapfile" (or "readarray")
command.

mapfile -t myarray < <(blah | sed)

If it's a NUL-delimited stream, and you're in bash 4.4 or higher, you
can use mapfile -d '' myarray < <(...) instead.

If it's a NUL-delimited stream but you're in bash 4.3 or older, then
you have to use a loop.

myarray=()
while IFS= read -r -d '' i; do
  myarray+=("$i")
done < <(...)
