Type mapping
| Value kind | in PostgreSQL | in EXCEL |
|---|---|---|
| Int | integer | 1234 (a real numeric cell) |
| Bigint | bigint | 9007199254740993 (exact only while the cell stays text) |
| Decimal | numeric(p,s) | 1234.56 (numeric cell, format controls the displayed decimals) |
| Float | double precision | 1.234E+10 (numeric cell) |
| Text | varchar(n) | text cell; leading zeros survive only if the column is text |
| Long text | text | text cell; wraps inside the cell rather than the row |
| Date | date | a serial number plus a date cell format |
| Datetime | timestamp | a serial number plus a date-time cell format |
| Binary | bytea | not representable as data |
| Boolean | boolean | TRUE / FALSE (a real boolean cell) |
| JSON | jsonb | a text cell; the quotes are part of the value |
