DFLib

DFLib ("DataFrame Library") is a lightweight pure Java implementation of a common DataFrame data structure. With DFLib you get essentially the same data manipulation tools you may be used to in SQL (such as queries and joins), only you can use them in-memory and over dynamically defined data structures.

It is somewhat close to Python pandas, except it is intended to be used with Java and other JVM languages.

DFLib comes with connectors for a variety of data formats: CSV, Excel, RDBMS (JDBC), Avro, JSON, etc.
