Field notes
The tool accepts structured text, converts it in either direction, and reports token counts against minified JSON rather than indented JSON. Its sample set includes an API response, a plain table, nested configuration, and records containing a list; the displayed outcomes range from TOON at 41% smaller to TOON at 33% larger. The page also exposes delimiter and indentation choices, including comma, tab, and pipe formats.
