TypeScript

Updated May 9, 2026

The TypeScript packages provide a fast data management framework built on the Fairspec standard and Polars DataFrames. They support a wide range of tabular formats — CSV, TSV, JSON, JSONL, XLSX, ODS, Arrow, Parquet, SQLite — plus inline data and Jupyter Notebook integration.

The pages in this section show how to load, validate, and save tables in each format.
