sort-json-by-key

This script will help you parse JSON file by key and sort it to separate files like [key].json. 📜

Example

Imagine you have a file, named city-list.json, which contain an array of objects like this:

[
    {
        "id": 3036216,
        "name": "Auga",
        "country": "FR"
    },
    {
        "id":2509475,
        "name":"Villatobas",
        "country":"ES"
    },
    {
        "id":3127817,
        "name":"Bordalba",
        "country":"ES"
    },
    {
        "id":6295630,
        "name":"Earth"
    }
]

... and we need to get separate files by key's value.

FR.json

[
    {
        "id": 3036216,
        "name": "Auga",
        "country": "FR"
    }
]

ES.json

[
    {
        "id":2509475,
        "name":"Villatobas",
        "country":"ES"
    },
    {
        "id":3127817,
        "name":"Bordalba",
        "country":"ES"
    }
]

For additional this script will create two files

_.json for not found values

[
    {
        "id":6295630,
        "name":"Earth"
    }
]

_keyList.json

["FR","ES",null]
