Type mapping
| Value kind | in CSV | in TSV |
|---|---|---|
| Text | quoted only when it contains a comma or a quote | unquoted; a tab in the value splits the column |
| Long text | must be quoted; line breaks inside force multi-line records | unquoted; newlines break the row |
| Binary | not representable - base64 or hex string | not representable |
| Boolean | TRUE / FALSE, or 1 / 0 depending on the writer | TRUE / FALSE |
| JSON | the whole JSON value quoted, with internal quotes doubled | the whole JSON value as-is (its own quotes stay) |
Dialect differences
Both CSV and TSV are file formats, so what differs below is how each one chooses to represent a value.

|---|---|---|
| identifiers | Double quotes; a literal quote is doubled ("" ) | Rarely used, which is exactly why tabs in data break it |
| binary | Not supported | Not supported - must be encoded |
| separator | Comma "," | Tab |
