[Python-ideas] Serialization of CSV vs. JSON

[Calvin Spealman]

First, this list is not appropriate. You should ask such a question in

Second, JSON is a specific serialization format that explicitly rejects
datetime objects in *all* the languages with JSON libraries. You can only
use date objects in JSON if you control or understand both serialization
and deserialization ends and have an agreed representation.
