Reading from file:

$ cat <<EOF > data.json
{
  "name": "John",
  "cars": [
    {
      "brand": "Ford",
      "type": "Taunus"
    },
    {
      "brand": "Nissan",
      "type": "Micra"
    }
  ]
}
EOF

$ json-flatten data.json
{ '/name': 'John',
  '/cars/0/brand': 'Ford',
  '/cars/0/type': 'Taunus',
  '/cars/1/brand': 'Nissan',

With input from stdin:

$ cat data.json | json-flatten
{ '/name': 'John',
  '/cars/0/brand': 'Ford',

  '/cars/1/brand': 'Nissan',
  '/cars/1/type': 'Micra' }
