request for @JohnWHamilton or @lauraGgit to test / review this simple script

To be clear, you want to convert the giant data.json JSON into a CSV that you can use within Excel, yes?

As an alternate to Python and dealing with pip and possible virtualenvs, can use Homebrew with a few commands that could just be put into a bash script.

brew install csvkit jq

curl -s -o fedramp-data.json https://raw.githubusercontent.com/18F/fedramp-data/master/data/data.json

For CSPs:
jq .data.Providers < fedramp-data.json | in2csv -f json > fedramp-providers.csv

For 3PAOs:
jq .data.Assessors < fedramp-data.json | in2csv -f json > fedramp-assessors.csv

Both fedramp-providers.csv and fedramp-assessors.csv open fine in Excel from local testing.

Here's a simple version of the script:

#!/bin/sh
#
# Convert FedRAMP Marketplace data from JSON into CSV
#
# Requires: `brew install csvkit jq`
#

set -e

FEDRAMP_DATA=$(mktemp -t fedramp-data)

curl -s -o $FEDRAMP_DATA https://raw.githubusercontent.com/18F/fedramp-data/master/data/data.json

META_DATE=$(jq -r .meta.Created_At < $FEDRAMP_DATA | cut -f 1 -d 'T')

jq .data.Providers < $FEDRAMP_DATA | in2csv -f json > fedramp-providers-$META_DATE.csv

jq .data.Assessors < $FEDRAMP_DATA | in2csv -f json > fedramp-assessors-$META_DATE.csv

rm $FEDRAMP_DATA
