Common Lisp Package: DATA-TABLE-TEST


Data Table

A Common Lisp library providing a data-table data-structure that has rows of data and column names and types

  • reading/writing values by row/column or index
  • combining data-tables as overlapping square regions
  • pulling sub tables from a data table
  • comparing data from two data-tables
  • conversion from data-tables of strings into data-tables of lisp-values, automatically guessing types if necessary
  • converting from / two other common-lisp data-structures (lists of alists/plists)


  • easier interaction with databases by having a common data-structure that can be queried and inserted
  • generating complex reports that contain multiple sections on a single spreadsheet of data
  • make getting/setting values anywhere in the results easier
