Linux: Only include items when value is more than 0

I use the following code to identify the top 200 CPU-hogging processes and return results in JSON format:
# Thanks simon3270 and jb1dev
cat ps.txt | sort | awk '{if (s == $1){n=n+$2} else {if (s != ""){print s " " n};s=$1;n=$2}}END{print s " " n}' | sort -rn -k +2 | awk 'BEGIN{print "{\"hogs\":{"}NR <= 200{printf " \"%s\":%.1f",$1,$2; printf ","} END{print "}}"}'
#
# or
#
ps -eo "%c %C" | sort | awk '{if (s == $1){n=n+$2} else {if (s != ""){print s " " n};s=$1;n=$2}}END{print s " " n}' | sort -rn -k +2 | awk 'BEGIN{print "{\"hogs\":{"}NR <= 200{printf " \"%s\":%.1f",$1,$2; printf ","} END{print "}}"}' 

Open in new window

(See the attached file, ps.txt)

I want all processes with the value of 0 to be excluded.  So the results should only contain an item if the value is more than 0.  Also, the last item should not have a comma after it.
ps.txt

You sample input contains the first line "COMMAND %CPU"

Do you want this line to be removed from the output?

cat ps.txt | grep -v '%CPU' | grep -v '0.0' | sort | awk '{if (s == $1){n=n+$2} else {if (s != ""){print s " " n};s=$1;n=$2}}END{print s " " n}' | sort -rn -k +2 | awk 'BEGIN{print "{\"hogs\":{"}NR <= 200{ if(NR != 1) { printf ", " } printf " \"%s\":%.1f",$1,$2; } END{print "}}"}'
