kaspersorensen commented on issue #230: dev/add datatypes to excel columns URL: https://github.com/apache/metamodel/pull/230#issuecomment-535814659 It would have been nice to have a small discussion about this change before doing the PR because I feel like there's maybe a few things I would have liked to do differently: * The idea of detecting column type seems general enough that we should have a facility for it as a decorator pattern or such. * The PR does not do anything to ensure conversion of values to conform with the data types. I know we have a converter API for that in the core module. * I do like the change from VARCHAR to STRING. For the sake of separating concerns I would do that in a separate PR though.
