Convert one JSON to another

JSON processor

Simply convert one JSON to another.

• Easy to use. Create a simple JSON conversion schema and pass it to processor
• Rich. It uses jsonpointer so you can create complex processors

Example

from json_processor import json_process

schema = {
    "type": "object",
    "value": {
        "simple_key": "Just a string",
        "values": {
            "type": "array",
            "from": {
                "type": "jsonpointer",
                "value": "/data/items"
            },
            "value": {
                "type": "object",
                "value": {
                    "id": {
                        "type": "jsonpointer",
                        "value": "/$value/foreign",
                        "cast": "integer"
                    },
                    "name": {
                        "type": "jsonpointer",
                        "value": "/$value/name"
                    }
                }
            }
        }
    }
}

data = {
    "data": {
        "items": [
            {
                "foreign": "100",
                "name": "Item 1"
            },
            {
                "foreign": "150",
                "name": "Item 2"
            }
        ]
    }
}

print(json_process(schema, data))

# Outputs:
# {'simple_key': 'Just a string', 'values': [{'id': 100, 'name': 'Item 1'}, {'id': 150, 'name': 'Item 2'}]}
