Frequently asked questions
- What if objects have different keys?
- The column list is the union of every object's keys; missing keys become NULL for that row.
- How are types mapped?
- Numbers and booleans are emitted unquoted (TRUE/FALSE); nested objects/arrays are JSON-stringified into a quoted string; null becomes NULL.
