Type mapping
| Value kind | in CSV | in TXT |
|---|---|---|
| Int | 1234 | 1234, or right-aligned in a fixed-width column |
| Text | quoted only when it contains a comma or a quote | written as-is; padding depends on the chosen layout |
| Long text | must be quoted; line breaks inside force multi-line records | written as-is |
| Date | 2026-09-18 | whatever the writer chose |
| Datetime | 2026-09-18 14:30:00 | whatever the writer chose |
| Binary | not representable - base64 or hex string | not representable |
| Boolean | TRUE / FALSE, or 1 / 0 depending on the writer | Y / N, or 1 / 0, or TRUE / FALSE |
| JSON | the whole JSON value quoted, with internal quotes doubled | written as-is |
Dialect differences
Both CSV and TXT are file formats, so what differs below is how each one chooses to represent a value.
| Property | in CSV | in TXT |
|---|---|---|
| identifiers | Double quotes; a literal quote is doubled ("" ) | None by convention |
| dates | Conventional text: 2026-09-18 or 2026-09-18 14:30:00 | Whatever the writer produced; no convention is guaranteed |
| separator | Comma "," | Whatever was chosen - often fixed column widths |
| shape | Flat table, optional header row | Free form; a parser has to be told the layout |
| ceiling | No formal limit; row count bounded by memory | No formal limit |
