| Float | 1.234e+10 | 1.234E+10 (numeric cell) |
| Text | unquoted; a tab in the value splits the column | text cell; leading zeros survive only if the column is text |

Dialect differences
Both TSV and EXCEL are file formats, so what differs below is how each one chooses to represent a value.
| Property | in TSV | in EXCEL |

| dates | Conventional text: 2026-09-18 or 2026-09-18 14:30:00 | Stored as a serial number; only the cell format makes it lo... |
| binary | Not supported - must be encoded | Only as text or an embedded object, not as a data column |
| separator | Tab | Cells, not delimiters |
| encoding | No declaration - UTF-8 works only with a BOM | UTF-8 internally, declared in the package |
| typing | None - every field is text | Real cell types: text, number, date, boolean, error |
| shape | Flat table, optional header row | Multiple sheets, each a flat grid |
| ceiling | No formal limit | 1,048,576 rows x 16,384 columns per sheet; 255 sheets per w... |
