Tools

Small tools for useful jobs.

Browser-based utilities for working with data, text, and files—designed to stay simple, fast, and private.

These first tools process their input in your browser. There is no account, upload server, or content analytics behind them.

Convert flat JSON records and standards-aware CSV text locally in your browser.

Processed locally

Clean, normalize, sort, and deduplicate lines of text without sending them anywhere.

Processed locally

Tools are repeat-use utilities. Smaller prototypes, demonstrations, and games will have a separate home under Experiments when they exist.
