How to convert a json response into yaml in bash

Question

I read data from a json file with jq. I wanna append the results into a yaml file, but I dont get it working. I am quite new to shell programming. My goal is to append that

Answer 1

Another oneliner:

python -c 'import yaml, sys; print(yaml.dump(yaml.load(open(sys.argv[1])), default_flow_style=False))' input.json

(exploiting the fact that valid json is also valid yaml)

And yaml to json:

python -c 'import yaml, json, sys; print(json.dumps(yaml.load(open(sys.argv[1])), indent=2))' input.yaml
