If you need parse exactly the same format, as you’ve shown in you question, it’s fairly easy to create something e.g. perl/awk/sed script.

for instance:

################# tst.awk #################
BEGIN {FS = "," }
{
split($1, m, "\ ")
printf "%s", "{ "
printf "%s",$2
printf "%s",$3
printf "%s",$5
printf "%s",$4
printf "reason: %s %s %s %s \"%s\"\n", m[6], m[7], m[8], m[9], m[10]
print " }”

}
#############################################


result:

echo 2018/01/10 06:26:31 [error] 13485#13485: *64285471 limiting connections by zone "rl_conn", client: xx.xx.xx.xx, server: www.xyz.com, request: "GET /api/xyz HTTP/1.1", host: "www.xyz.com" | awk -f /tmp/test.awk
{ client: xx.xx.xx.xx server: www.xyz.com host: www.xyz.com request: GET /api/xyz HTTP/1.1reason: limiting connections by zone "rl_conn"
}
