jello

A command-line JSON processor using Python syntax. More information: https://github.com/kellyjonbrazil/jello.

  • Pretty-print JSON or JSON-Lines data from stdin to stdout:

cat {{file.json}} | jello

  • Output a schema of JSON or JSON Lines data from stdin to stdout (useful for grep):

cat {{file.json}} | jello -s

  • Output all elements from arrays (or all the values from objects) in JSON or JSON-Lines data from stdin to stdout:

cat {{file.json}} | jello -l

  • Output the first element in JSON or JSON-Lines data from stdin to stdout:

cat {{file.json}} | jello _[0]

  • Output the value of a given key of each element in JSON or JSON-Lines data from stdin to stdout:

cat {{file.json}} | jello '[i.{{key_name}} for i in _]'

  • Output the value of multiple keys as a new JSON object (assuming the input JSON has the keys key_name1 and key_name2):

cat {{file.json}} | jello '{"{{key1}}": _.{{key_name1}}, "{{key_name}}": _.{{key_name2}}}'

  • Output the value of a given key to a string (and disable JSON output):

cat {{file.json}} | jello -r '"{{some text}}: " + _.{{key_name}}'
