Mac cli to convert yaml to json

Question

is there a quick way to convert bunch of yaml files to json files. I looked at yaml2json and it is not working (throws some exception)

Thanks

Answer 1

Adding answer because there's no answer for the latest version for yq (except in comments).

brew install yq

yq -j eval test.yaml

Answer 2

Use the real yq (not python yq) from https://github.com/mikefarah/yq

brew reinstall yq

Then run:

/usr/local/bin/yq r deployment.yaml -j -P > deployment.json

Meaning of the arguments, from --help:

  -P, --prettyPrint    pretty print, shorthand for '... style = ""'
  -j, --tojson         output as json. Set indent to 0 to print json in one line 

Answer 3

You could pipe your YAML to this (requires having pyYAML installed)

python -c 'import yaml; import json; import sys; print(json.dumps(yaml.safe_load(sys.stdin)));'

Answer 4

With current releases of yq (v4.24.5):

yq eval -o json my.yaml > my.json

Note that (as of 4.18.1) eval is the default command when none is supplied to yq, which means that this works perfectly fine, as well.

yq -o json my.yaml > my.json
