Type mapping
| Value kind | in TSV | in CSV |
|---|---|---|
| Text | unquoted; a tab in the value splits the column | quoted only when it contains a comma or a quote |
| Long text | unquoted; newlines break the row | must be quoted; line breaks inside force multi-line records |
| Binary | not representable | not representable - base64 or hex string |
| Boolean | TRUE / FALSE | TRUE / FALSE, or 1 / 0 depending on the writer |
| JSON | the whole JSON value as-is (its own quotes stay) | the whole JSON value quoted, with internal quotes doubled |
