Practical Data: Chrome extension applies AI semantic formatting to web tables
calabi_and_yau · x · 2026-11-11
Practical Data is a Chrome extension that applies conditional formatting to data tables as you browse, turning any table on the web into a visualization.
- A decision model infers each column's semantics: which direction is "better" (e.g., lower ERA), and which columns are identifiers like jersey numbers or zip codes that should be ignored
- Handles messy data parsing automatically, avoiding the pitfalls of uniform "big = green" rules
- Open source with docs and tests, available on the Chrome Web Store
Sharers call it a wild rethinking of spreadsheet UX: semantically highlighting cells instead of writing Excel demos.
