In the examples, I have seen on the net
You can use the command line
echo "show stat" | nc -U /var/lib/haproxy/stats
Which is very ugly in the output. Columns don't match and it is difficult to see what is going on.

Is there a good way to clean this up and make it more readable.

I found the following to be useful
watch 'echo "show stat" | nc -U /var/lib/haproxy/stats | cut -d "," -f 1,2,5-11,18,24,27,30,36,50,37,56,57,62 | column -s, -t'
It will produce output as follows
Every 2.0s: echo "show stat" | nc -U /var/lib/haproxy/stats | cut -d "," -f 1,2,5-11,18,24,27,30,36,50,37,56,57,62 | column -s, -t Thu Mar 30 15:01:19 2017
# pxname svname scur smax slim stot bin bout dreq status lastchg pid throttle rate_max check_status cli_abrt lastsess last_chk ttime
somedb FRONTEND 1 1 512 1 0 0 0 OPEN 1 1
appp01 coolappss-01 1 1 1 0 0 no check 1 1 0 2973 0
coredb BACKEND 1 1 52 1 0 0 0 UP 2975 1 1 0 2973 0
Now the columns are lined up and any only columns I am interested in are being shown.
If you want to know what the column numbers are for this cut command will help.
echo "show stat" | nc -U /var/lib/haproxy/stats | grep "#" | tr ',' '\n' | nl
