Float	`1.234e+10`	`1.234e10 (number)`
Text	`unquoted; a tab in the value splits the column`	`"text" (string)`
Long text	`unquoted; newlines break the row`	`"multi-line\ntext" (escaped newline inside a string)`
Date	`2026-09-18`	`"2026-09-18" (string)`
Datetime	`2026-09-18 14:30:00`	`"2026-09-18T14:30:00Z" (string)`

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`
