The general idea on importing table shaped date is to use each column as a relation and each row as an entity. So you can use a Clojure library to read in CSV or Excel, extract a cleaned up version of each row from the table into a hash-map {:column1-name value1, :column2-name value ...} and then transact all of them into Datahike (or DataScript or Datomic). In Datahike and DataScript you can omit declaring a Schema if your data is shaped in an odd way and you do not want to do the upfront work.

Are there breaking changes between 0.2.0 and .1?
I am getting: No implementation of method: :-slice of protocol: #'datahike.index/IIndex found for class: incognito.base.IncognitoTaggedLiteral
