About

Tools for unfamiliar data, made in the open.

Tabalyst is an open-source, local-first toolkit for understanding structured data. This page says where it comes from, what it stands for and who makes it.

Vision

Simple. Clear. Smart.

Three words guide what Tabalyst does and how it is written. Each one is a test that every page and every command has to pass, and each one has a proof you can check.

Simple. Clear. Smart.

  • Simple

    Reduce friction and needless complexity. One line installs it, and one command reports a file or hundreds of them.

    See the commands

  • Clear

    Make data understandable and results reusable: an HTML report for people, a JSON profile for systems.

    See the two outputs

  • Smart

    Detect, adapt and decide what can reasonably be automated. Tabalyst finds the right table or collection of a file and says so when it cannot choose.

    How Tabalyst Inspect chooses

Smart does not mean artificial intelligence. The current Tabalyst has no AI component. Its analysis is deterministic: it applies explicit rules and settings, and it does not use a model. If that changes, this page will say so.

Origin

Where it comes from

Tabalyst was born from a concrete need met while teaching artificial intelligence and ETL: before you work with a dataset, you have to know what it contains. It started as a Python library that wrote an HTML report and a JSON profile from a CSV file.

It grew past that first need. Tabalyst now reads four formats and has tools around the report, and its use goes beyond the classroom, to people who work with data every day.

Today

From a report to a toolkit

Tabalyst is the name of the whole toolkit. Tabalyst Report is its first and best-known tool: it is available today. Tabalyst Inspect, Tabalyst Scan and Tabalyst Sample are available too. Tabalyst Generate is in beta, and Tabalyst Explore and Tabalyst Online are announced, not available.

A tool is announced only when it is real or clearly marked as future.
