Dialect differences
Both TSV and JSON Array are file formats, so what differs below is how each one chooses to represent a value.
| Property | in TSV | in JSON Array |
|---|---|---|
| identifiers | Rarely used, which is exactly why tabs in data break it | Double quotes; backslash escapes |
| dates | Conventional text: 2026-09-18 or 2026-09-18 14:30:00 | No date type: dates arrive as strings and the reader must p... |
| binary | Not supported - must be encoded | Not supported natively - base64 inside a string |
| separator | Tab | Braces and commas |
| encoding | No declaration - UTF-8 works only with 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 | Whole document is usually parsed into memory |
