Overview

Tablesaw is Java for data science. It includes a dataframe and a visualization library, as well as utilities for loading, transforming, filtering, and summarizing data. It's fast and careful with memory. If you work with data in Java, it may save you time and effort. Tablesaw also supports descriptive statistics and integrates well with the Smile machine learning library.

Tablesaw features

  • Export data to CSV, JSON, HTML or Fixed Width files.
  • Combine tables by appending or joining
  • Add and remove columns or rows
  • Sort, Group, Query
  • Map/Reduce operations
