Minifies and escapes a json file. I use this for minifying json key files from GCP

jsonmin

#!/usr/bin/env bash

usage() {
  echo "./jsonmin <INFILE> <OUTFILE>"
  echo "   INFILE: File to be minified"
  echo "  OUTIFLE: File to save minified json as"
}

INFILE=$1
OUTFILE=$2

if [[ -z "$INFILE" ]]; then
  echo "Error: Missing parameter.  Expect 2."
  usage
  exit 1
fi

if [[ -z "$OUTFILE" ]]; then
  echo "Error: Missing parameter.  Expect 2."
  usage
  exit 1
fi

if ! [ -x "$(command -v python)" ]; then
  echo 'Error: python is not installed.' >&2
  exit 1
fi

if ! [ -x "$(command -v jq)" ]; then
  echo 'Error: jq is not installed.' >&2
  exit 1
fi

if [[ $INFILE == $OUTFILE ]]; then
  echo 'Error: The INFILE and OUTFILE can not be the same file.'
  exit 1
fi

python -c 'import json, sys;json.dump(json.load(sys.stdin), sys.stdout)' < $INFILE | jq -aR . > $OUTFILE

echo "Successfully minified ${INFILE} to ${OUTFILE}"
