How to format large JSON file in command line
There are several tools that can be used to format a large JSON file.
Prettier (if you have node.js and npx installed):
npx run prettier input_json.json > formatted_json.json
With python:
cat input_json.json | python -m json.tool > formatted_json.json
# json.tool uses 4 spaces as indent by default, we can change it:
cat input_json.json | python -m json.tool --indent 2 > formatted_json.json
With jq:
jq '.' input_json.json > formatted_json.json
Reminder: to open a large file in vim / nvim it is better to run it with -u NONE: nvim -u NONE formatted_json.json.
