FlexTable (flextablejs) is a JavaScript library that provides a class with a simple API to work with tables (headers, rows, columns, sort, format) facilitating the analysis and data manipulation.

CSV Types (csv-types-js) is a JavaScript library to parse CSV strings (comma separated values and text files with fields delimited by a character) and produce a JavaScript AST (abstract syntax tree) with the data. It also supports types specs: multiple headers-values (tables) per csv string.
