What is a semicolon-delimited file?
A semicolon-delimited file is a plain-text file where each line is one record and a semicolon ; separates the fields. It is the usual CSV variant in locales where the decimal separator is a comma, so a comma inside a number would otherwise be ambiguous.

Type mapping
| Value kind | in Semicolon-delimited text | in JSON |
|---|---|---|
| Int | 1234 | 1234 (number) |
| Decimal | 1234.56 | 1234.56 (number) |
| Float | 1.234e+10 | 1.234e10 (number) |
| Text | quoted only when it contains a semicolon or a quote | "text" (string) |
| Long text | must be quoted; line breaks inside force multi-line records | "multi-line\ntext" (escaped newline inside a string) |
| Date | 2026-09-18 | "2026-09-18" (string) |
| Datetime | 2026-09-18 14:30:00 | "2026-09-18T14:30:00Z" (string) |
| Binary | not representable - base64 or hex string | "base64:..." (string) |
| Boolean | TRUE / FALSE, or 1 / 0 depending on the writer | true / false (boolean) |
| JSON | the whole JSON value quoted, with internal quotes doubled | nested object or array, kept as structure |
Dialect differences
Both Semicolon-delimited text and JSON are file formats, so what differs below is how each one chooses to represent a value.
| Property | in Semicolon-delimited text | in JSON |
|---|---|---|
| identifiers | Double quotes; a literal quote is doubled ("" ) | Double quotes; backslash escapes |
| dates | Dates often use D/M/Y or D.M.Y in European exports | No date type: dates arrive as strings and the reader must p... |
| binary | Not supported | Not supported natively - base64 inside a string |
| separator | Semicolon ";" | Braces and commas |
| encoding | Often ANSI or Latin-1 in European exports; UTF-8 needs a BOM | UTF-8 by definition |
| typing | None - every field is text | string, number, boolean, null, object, array - no date type |
| shape | Flat table, optional header row | Nested objects and arrays |
| ceiling | No formal limit; row count bounded by memory | Whole document is usually parsed into memory |
