Delimiters supported

Comma, semicolon, tab, pipe — select above. Quoted fields with commas inside are handled correctly.

Smart type inference

Numbers, booleans (true/false), and null/empty values are auto-typed in JSON output rather than kept as strings.

JSON → CSV

Accepts array of objects (keys become headers) or array of arrays (row per row). Nested objects are stringified.
