Dialect differences
Both HTML and CSV are file formats, so what differs below is how each one chooses to represent a value.
| Property | in HTML | in CSV |
|---|---|---|
| identifiers | Attribute values in quotes; entities for reserved characters | Double quotes; a literal quote is doubled ("" ) |
| dates | Whatever text was rendered | Conventional text: 2026-09-18 or 2026-09-18 14:30:00 |
| binary | data: URIs inside src attributes | Not supported |
| separator | Tags, not delimiters | Comma "," |
| encoding | Declared in a meta charset tag or the HTTP header | No declaration - UTF-8 works only with a BOM |
| typing | None | None - every field is text |
| shape | Free form; tables are row/column structures inside markup | Flat table, optional header row |
| ceiling | No formal limit | No formal limit; row count bounded by memory |
