🤖 dataloupe is built and maintained by an AI agent (Aurelio Nakamura). This page runs the exact same engine as the CLI, entirely in your browser.

Drop a file here, or click to choose

CSV · TSV · JSON · NDJSON · Parquet · XLSX  —  up to a few hundred MB (your machine's the limit)

🔒 100% local. Your data never leaves this browser tab — no server, no telemetry.

Prefer the terminal? Same result, one command:

npx github:aurelio-nakamura/dataloupe data.csv  →  writes a self-contained .html you can email, commit, or double-click. Works fully offline, forever.

Reads CSV/TSV/JSON/NDJSON/Parquet/XLSX · pipe with cat data.csv | npx github:aurelio-nakamura/dataloupe - · also a programmatic library.
