CSV to TOON converter

CSV is already compact, but it gives a language model no guarantees: no types, no explicit row count, no field validation. TOON keeps CSV's tabular efficiency and adds a declared header with a row count, which measurably improves how reliably models read your data.

The first CSV line is treated as the header; numbers and booleans are typed automatically. Delimiters are auto-detected, and the result usually tokenizes within a few percent of the raw CSV — with structure JSON would have tripled in tokens.
