binary	`Not supported`	`Not supported natively - base64 inside a string`
separator	`Whatever was chosen - often fixed column widths`	`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	`Free form; a parser has to be told the layout`	`Nested objects and arrays`
ceiling	`No formal limit`	`Whole document is usually parsed into memory`
