I’m often dealing with little bits of JSON, and sometimes it’s helpful to
pretty-print them for readability.
Python has a handy tool to make that easy on the command line: json.tool.
E.g.
echo '{"foo": "bar", "thing": { "baz": 42 } }' | python -m json.tool
prints:
{
"foo": "bar",
"thing": {
"baz": 42
}
}
If you’re on Mac, you can convert JSON in the clipboard to its pretty-printed
form with:
pbpaste | python -m json.tool | pbcopy
Ubuntu equivalent with xclip:
xclip -selection clipboard -o | python -m json.tool | tee >(xclip -selection clipboard)
I have that aliased to pcj (for “pretty print clipboard json”).
Mac:
alias pcj='pbpaste | python -m json.tool | pbcopy'
Ubuntu:
alias pcj='xclip -selection clipboard -o | python -m json.tool | tee >(xclip -selection clipboard)'
The three clipboard JSON manipulation aliases I have set up are:
alias jec='xclip -selection clipboard -o | python3 -c "import sys;import json;print(json.dumps(sys.stdin.read().strip()))" | tee >(xclip -selection clipboard)'
alias pcj='xclip -selection clipboard -o | python3 -m json.tool | tee >(xclip -selection clipboard)'
alias mcj='xclip -selection clipboard -o | python3 -c "import sys;import json;print(json.dumps(json.loads(sys.stdin.read()),separators=(\",\",\":\")))" | tee >(xclip -selection clipboard)'
