Flatten/Explode JSON objects.

## Installation

```bash

pip install flatsplode

```

## Usage

Use the `flatsplode()` function to recursively flatten and explode complex JSON objects.

Import the `flatsplode` function:

```python

from flatsplode import flatsplode

```

Create a sample object to flatsplode:

```python

item = {

    'id': '78e5b18c',

    'keywords': [

        'fizz',

        'buzz'

    ],

    'attrs': [

        {'name': 'color', 'value': 'green'},

        {'name': 'size', 'value': 42},

    ],

    'deep': {

        'nested': {

            'keys': {

                'fizz': 'buzz',

                'jazz': 'fuzz',

            }

        }

    }

}

```

Calling `flatsplode(item)` will return a generator. Use `list()` to expand:

```python

list(flatsplode(item))

[

    {

        'id': '78e5b18c',

        'keywords': 'fizz',

        'attrs.name': 'color',

        'attrs.value': 'green',

        'deep.nested.keys.fizz': 'buzz',

        'deep.nested.keys.jazz': 'fuzz'

    },

    {

        'id': '78e5b18c',

        'keywords': 'fizz',

        'attrs.name': 'size',

        'attrs.value': 42,

        'deep.nested.keys.fizz': 'buzz',

        'deep.nested.keys.jazz': 'fuzz'

    },

    {

        'id': '78e5b18c',

        'keywords': 'buzz',

        'attrs.name': 'color',

        'attrs.value': 'green',

        'deep.nested.keys.fizz': 'buzz',

        'deep.nested.keys.jazz': 'fuzz'

    },

    {

        'id': '78e5b18c',

        'keywords': 'buzz',

        'attrs.name': 'size',

        'attrs.value': 42,

        'deep.nested.keys.fizz': 'buzz',

        'deep.nested.keys.jazz': 'fuzz'

    }

]

```

You can also provide your own join-character:

```python

list(flatsplode(item, '/'))

[

    {

        'id': '78e5b18c',

        'keywords': 'fizz',

        'attrs/name': 'color',

        'attrs/value': 'green',

        'deep/nested/keys/fizz': 'buzz',

        'deep/nested/keys/jazz': 'fuzz'

    },

    …

]

```

Flatsploding is useful when converting objects to pandas DataFrame matrices:

```python

import pandas

from flatsplode import flatsplode

pandas.DataFrame(flatsplode(item))

```

Pandas also has a built in normalizer that will flatten (but not explode) your data:

```python

from flatsplode import explode

pandas.json_normalize(explode(item))

```

Result:

```plaintext

         id attrs.name attrs.value deep.nested.keys.fizz deep.nested.keys.jazz keywords

0  78e5b18c      color       green                  buzz                  fuzz     fizz

1  78e5b18c       size          42                  buzz                  fuzz     fizz

2  78e5b18c      color       green                  buzz                  fuzz     buzz

3  78e5b18c       size          42                  buzz                  fuzz     buzz

```
