Dialect differences
JSON Lines is a file format and xBase is a database server, so the target has to be told the types the file never carried - the rows below are where the two sides diverge.
| Property | in JSON Lines | in xBase |
|---|---|---|
| port | — | (file-based) |
| identifiers | Double quotes; backslash escapes (a newline inside a string... | — |
| row limit | — | (driver dependent) |
| dates | No date type: dates arrive as strings | Date (D) |
| long text | — | Memo (M) |
| binary | Not supported natively - base64 inside a string | — |
| separator | Newline between records | — |
| encoding | UTF-8 by definition | — |
| typing | Same as JSON, but records cannot nest across lines | — |
| shape | Flat stream | Tables of rows and columns |
| ceiling | Streams, so it scales past what a single JSON document can ... | — |
