Type mapping
| Value kind | in CSV | in XML |
|---|---|---|
| Int | 1234 | <int>1234</int> |
| Bigint | 9007199254740993 | <bigint>9007199254740993</bigint> |
| Decimal | 1234.56 | <decimal>1234.56</decimal> |
| Float | 1.234e+10 | <float>1.234e10</float> |
| Text | quoted only when it contains a comma or a quote | <char>text</char> |
| Long text | must be quoted; line breaks inside force multi-line records | <text>multi-line text</text> (entities for & <) |
| Date | 2026-09-18 | <date>2026-09-18</date> (xs:date with an XSD) |
| Datetime | 2026-09-18 14:30:00 | <datetime>2026-09-18T14:30:00Z</datetime> (xs:dateTime) |
| Binary | not representable - base64 or hex string | <blob>base64...</blob> (xs:base64Binary) |
| Boolean | TRUE / FALSE, or 1 / 0 depending on the writer | <bool>true</bool> |
| JSON | the whole JSON value quoted, with internal quotes doubled | escaped inside an element, or its own sub-tree |
Dialect differences
Both CSV and XML are file formats, so what differs below is how each one chooses to represent a value.
| Property | in CSV | in XML |
|---|---|---|
| identifiers | Double quotes; a literal quote is doubled ("" ) | Attribute values in quotes; entities (& < >) for ... |
| dates | Conventional text: 2026-09-18 or 2026-09-18 14:30:00 | Text (xs:date / xs:dateTime when an XSD is in play) |
| binary | Not supported | base64Binary / hexBinary inside text |
| separator | Comma "," | Tags, not delimiters |
| encoding | No declaration - UTF-8 works only with a BOM | Declared in the XML declaration |
| typing | None - every field is text | None in the markup itself |
| shape | Flat table, optional header row | Arbitrary tree |
| ceiling | No formal limit; row count bounded by memory | Whole document is usually parsed into memory |
