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 |
