# Separate responses with new lines, delete empty lines and save into c2.txt:
cat Contributors.txt | sed 's/{\"response\"/\n{\"response\"/g' | sed '/^$/d' > c2.txt

# generate CSV from JSON (asd.py: http://pastebin.com/MmVXisbU )
# c2.csv is the full list
cat c2.txt | ./asd.py > c2.csv

# delete the "$" character, select lines where display_amount > 150 (tablet); save c3.csv
cat c2.csv | tr -d '$' | awk -F '\t' '$3 > 150 { print  $0 }' > c3.csv

# reverse the lines (maybe fix header by hand :-) )
tac c3.csv > c4.csv
