TXT → Semicolon-delimited text reference
Type mapping
| Value kind | in TXT | in Semicolon-delimited text |
|---|---|---|
| Int | 1234, or right-aligned in a fixed-width column | 1234 |
| Text | written as-is; padding depends on the chosen layout | quoted only when it contains a semicolon or a quote |
| Long text | written as-is | must be quoted; line breaks inside force multi-line records |
| Date | whatever the writer chose | 2026-09-18 |
| Datetime | whatever the writer chose | 2026-09-18 14:30:00 |
| Binary | not representable | not representable - base64 or hex string |
| Boolean | Y / N, or 1 / 0, or TRUE / FALSE | TRUE / FALSE, or 1 / 0 depending on the writer |
| JSON | written as-is | the whole JSON value quoted, with internal quotes doubled |
Dialect differences
Both TXT and Semicolon-delimited text are file formats, so what differs below is how each one chooses to represent a value.
| Property | in TXT | in Semicolon-delimited text |
|---|---|---|
| identifiers | None by convention | Double quotes; a literal quote is doubled ("" ) |
| dates | Whatever the writer produced; no convention is guaranteed | Dates often use D/M/Y or D.M.Y in European exports |
| separator | Whatever was chosen - often fixed column widths | Semicolon ";" |
| encoding | No declaration - UTF-8 works only with a BOM | Often ANSI or Latin-1 in European exports; UTF-8 needs a BOM |
| shape | Free form; a parser has to be told the layout | Flat table, optional header row |
| ceiling | No formal limit | No formal limit; row count bounded by memory |
