Google Forms group and count responses by date

1. Download responses as CSV (either from the GUI: File → Download → as CSV or curl -Ls [url]/export?format=csv)

Timestamp is the first field so let’s drop everything else:

csvcut -c 1 responses.csv

Then drop the timestamp and keep only the date

cut -f' ' -f 1

Sort and count and resort by date

sort | uniq -c | sort -k2 -n
