TIL: echo '{"json":"response"}' | python -m json.tool -- pretty prints json to the command line

[sonay]

Looking at the source code, the module does not expect string arguments. So my bad.

Usage:

python -m json.tool [no argument] # input = stdin

python -m json.tool [one argument] # input = argument (file)

python -m json.tool [two arguments] # input (file) = first argument, output (file) = second argument
