JSON and YAML are everywhere. Here are 10 tools that make working with them significantly easier.

1. jq

cat data.json | jq ‘.’ cat data.json | jq ‘.users[] | {name, email}’

2. yq

yq ‘.services.app.image’ docker-compose.yml yq -o json docker-compose.yml

3. fx — Interactive Viewer

curl api.example.com | fx

4. python -m json.tool

echo ‘{“a”:1}’ | python3 -m json.tool

5. yamllint

yamllint docker-compose.yml

6. dasel

dasel -f config.yml ‘.database.host’

7. gron

gron data.json | grep “email”

8. jless

cat data.json | jless

9. Miller (mlr)

mlr –icsv –ojson cat data.csv

10. jo
