Module provides flatten which is used to flatten structure of Aeson JSON Value as much as possible.

Examples

Basic objects

{ "a": { "b": 1 } } results in { "b": 1 }

{ "a": { "b": { "c": 1 } } } results in { "c": 1 }

{ "a": [ { "b": { "c": 1 } }, { "b": { "c": 2 } } ] } results in { "a": [ { "c": 1 }, { "c": 2 } ] }

Name conflicts result in data loss

{ "a": 1, "b": { "a": 2 } } results in { "a": 1 }

• I don't know yet whether this is a feature or a bug :)
