Dialect differences
Both JSON and TXT are file formats, so what differs below is how each one chooses to represent a value.
| Property | in JSON | in TXT |
|---|---|---|
| identifiers | Double quotes; backslash escapes | None by convention |
| dates | No date type: dates arrive as strings and the reader must p... | Whatever the writer produced; no convention is guaranteed |
| binary | Not supported natively - base64 inside a string | Not supported |
| separator | Braces and commas | Whatever was chosen - often fixed column widths |
| encoding | UTF-8 by definition | No declaration - UTF-8 works only with a BOM |
| typing | string, number, boolean, null, object, array - no date type | None - every field is text |
| shape | Nested objects and arrays | Free form; a parser has to be told the layout |
| ceiling | Whole document is usually parsed into memory | No formal limit |
