I recently came across the problem of needing to "pretty print" a json output to debug a JSON API call. The only script i came across was a .NET application?!?! anyway, a few lines of python did the trick (i guess 1 line of perl would've done the job, but it doesn't have a standard JSON library)


import sys
import json

x = json.load(sys.stdin)
print json.dumps(x, indent = 2)

pretty sophisticated, right? well... 10 minutes of googling solved by 1 minute of coding.. great

usage is obvious i guess...

Herbys-i7:~ herbert$ curl -s \
  "http://xxx/data/admin?cmd=listInactiveUsers&format=djson" \
  | jsontidy
  "users": [
      "username": "test5", 
      "id": "d3292a0c-d152-42b1-98d0-335ded789bc6"
      "username": "test2", 
      "id": "0d947487-bccc-4742-bf4e-0b0afeb2011f"

Of course you could also do it in one line.. how about using the following in your .bash_profile?

alias jsontidy='python -c "import sys,json;json.dump(json.load(sys.stdin), sys.stdout, indent=2)"'

Hey, we have Signatures !!! Great, isn't it ? ;)
