Created

This python recursive function flattens a JSON file or a dictionary with nested lists and/or dictionaries. The output is a flattened dictionary that use
dot-chained names for keys, based on the dictionary structure. This allows for reconstructing the JSON structure or converting it to
other formats without loosing any structural information.

| example: The following JSON document: | |
| {"maps":[{"id1":"blabla","iscategorical1":"0", "perro":[{"dog1": "1", "dog2": "2"}]},{"id2":"blabla","iscategorical2":"0"}], | |
| "masks":{"id":"valore"}, | |
| "om_points":"value", | |
| "parameters":{"id":"valore"}} | |
| will have the following output: | |
| {'masks.id': 'valore', 'maps.iscategorical2': '0', 'om_points': 'value', 'maps.iscategorical1': '0', | |
| 'maps.id1': 'blabla', 'parameters.id': 'valore', 'maps.perro.dog2': '2', 'maps.perro.dog1': '1', 'maps.id2': 'blabla'} |
